DET MasterBook · Course Book · Interactive editionFoundation · DET 60–95 · 19 exercises
This unit is for you if your Reading subscore is below about 95, or if you have never taken the Duolingo English Test (DET) and English reading still feels slow: you know many words when you hear them but hesitate when you see them alone, you are not sure how to finish a word when only half of it is on the screen, and the clock runs out before you reach the last question about a passage. At Foundation level you do not need to read faster. You need to know exactly what each Reading question asks for, use the small clues that decide most answers, and stop losing marks you could easily keep.
The DET gives you an overall score and four subscores, Reading, Listening, Writing and Speaking, each from 10 to 160 in steps of 5. Duolingo's 2026 Scoring Guide links 60–95 to CEFR B1, roughly IELTS 4 to 5.5. Many universities ask for about 105–120 overall, so Level 1 is not your final target, but it is the base everything else stands on. Your Reading subscore also feeds two of the combined subscores that universities can see: Comprehension (Reading with Listening) and Literacy (Reading with Writing). The DET is adaptive: when you answer well, the next questions become harder, and only harder questions open the higher scores. The careful habits in this unit are what move you onto that path. Requirements differ between universities and change often, so always check the current requirement for your course. FLC levels are our estimates, not official DET scores.
The DET is one continuous test of about an hour, taken at home on a computer. There is no separate "Reading section" with its own clock: Reading questions appear among the other question types, and each one has its own timer. Four question types give you your Reading subscore:
| Question type | What you do | Time | How many |
|---|---|---|---|
| Read and Select | see one word and decide: is it a real English word? Click Yes or No. | 5 seconds per word | 15–18 words |
| Fill in the Blanks | see one sentence with an unfinished word and type the missing end of the word | 20 seconds | 6–9 sentences |
| Read and Complete | see a short paragraph with several unfinished words and type the missing ends | 3 minutes per paragraph | 3–6 paragraphs |
| Interactive Reading | answer six questions, one at a time, about one passage | 7 or 8 minutes per set | 2–3 sets |
Formats, times and numbers are from Duolingo's DET Question Guide 2026. The exact number of each question type changes from test to test.
How each one is marked tells you how to work:
| Question | How it is marked | What this means for you |
|---|---|---|
| Read and Select | each word right or wrong; no click in 5 seconds counts as wrong | always click Yes or No |
| Fill in the Blanks | right or wrong; the spelling must be correct | a nearly right word scores nothing |
| Read and Complete | each unfinished word marked separately; the spelling must be correct | every word you finish correctly is a mark |
| Interactive Reading | Complete the Sentences: each blank marked separately. Highlight the Answer: partial credit. The other three: right or wrong. | answer all six questions before time runs out |
1. You cannot go back. Each answer is final, and each one helps the test choose your next question. Give every question your full attention when it is on the screen, not "later". 2. Never let a timer run out. An empty answer is a wrong answer. A careful best guess always has a chance; a blank has none.
Many students feel worried when the questions suddenly get harder, and start to rush. On an adaptive test, harder questions are usually good news: they mean you answered the earlier ones well. Keep using the same careful method. If the questions feel easy, do not relax either: every correct answer still counts.
Choose the best answer.
1 How long do you have to answer one word in Read and Select?
2 In Read and Complete, which part of the paragraph never has unfinished words?
3 In Fill in the Blanks, you type a word that has the right meaning but one letter is wrong. What happens?
4 How many questions are there about one Interactive Reading passage?
5 You answer several questions correctly. What usually happens next on the DET?
6 What range is the Reading subscore reported on?
What it tests: the size of your English vocabulary, and whether you recognise how English words are spelt. You see one word at a time and click Yes if it is a real English word or No if it is not. You have 5 seconds for each word, and you meet 15–18 words. There is nothing to read around the word: no sentence, no picture. You simply know it, or you work it out from its parts.
The fake words are made to look real. Most of them are built in one of four ways:
| How the fake word is made | Fake example | Why it is not English |
|---|---|---|
| A real word with one or two letters changed | garbon | looks like garden or carbon, but is neither |
| Real parts joined in a way English does not use | unhappiful, quickment | un-, happy and -ful are real, but English says unhappy; -ment joins verbs (enjoyment), not adjectives |
| A real word spelt wrongly | freind, beleive | the real words are friend and believe |
| A new word that only sounds English | thrasp, vorbid | easy to say, but they have no meaning |
Before a word: un- (unkind), dis- (disagree), re- (rewrite), mis- (misplace), pre- (preview). After a verb, making a noun: -ment (enjoyment), -tion (education), -er (teacher). After an adjective, making a noun: -ness (kindness). After a noun, making an adjective: -ful (careful), -less (careless). After an adjective, making an adverb: -ly (quickly). When a part is on the wrong kind of word (quickment, unhappiful), the word is fake.
British and American spellings are both real English words: colour and color, centre and center, neighbour and neighbor, travelled and traveled. If you were taught one spelling in school and see the other on the screen, the answer is still Yes.
A fake word that is one letter away from a word you know feels familiar, and familiar feels like "Yes". Garbon looks like garden; freind looks like friend. Before you click Yes, check that the word is the one you know, letter by letter, not just a word that looks like it.
Exam conditions: about 5 seconds per word. Write Yes for a real English word and No for a fake word. Cover the words you have done so you cannot go back.
In each group, only one word is real English. Choose it, and notice how the other three were made.
1 Which is a real English word?
2 Which is a real English word?
3 Which is a real English word?
4 Which is a real English word?
5 Which is a real English word?
What it tests: whether you can use the meaning and grammar of a sentence to rebuild one word. You see one sentence. One word in it is unfinished: you see the first part of the word, and you type the rest. You have 20 seconds. The answer is right or wrong, and the spelling must be correct. The missing word is always a noun, verb, adjective or adverb, never a small word such as the or of.
In this book, each _ is one missing letter. Four clues decide almost every answer:
| Clue | Ask yourself | Example |
|---|---|---|
| The letters you see | Which words start like this? | tic___: ticket, tickle… |
| The kind of word | Noun, verb, adjective or adverb? Singular or plural? Past or present? | an important disc_____: after an important we need a noun: discovery |
| Word partners | Which word usually goes with the words around it? | make a deci____: we make a decision |
| Same or opposite meaning nearby | Does the sentence contrast or repeat an idea? | nice but very expe_____: but signals a problem: expensive |
Sentence: The village was quiet during the day, but at night the streets were very no___.
Answer: noisy. After very we need an adjective. But tells us the night is the opposite of the day, and the opposite of quiet is noisy. A student who types noise has the right idea but the wrong kind of word (a noun), and the answer is marked wrong.
Some phrases that are common in Indian English are not standard international English, and the DET marks against the standard. We make a mistake (not do a mistake), we discuss a plan (not discuss about), and we cope with a problem (not cope up with). If a gap follows one of these phrases, choose the standard partner.
The DET accepts both British and American spelling (colour or color, travelled or traveled), so choose the spelling you are surest of. What it does not accept is a spelling that belongs to neither, such as colur or travaled. The test has no spell check, so a habit of trusting your phone's autocorrect will cost marks here.
Exam conditions: about 20 seconds each. Each _ is one missing letter. Write the full word.
You often know the start of the word but not its ending. Choose the full word that fits the sentence.
1 Her explanation of the homework was very help___.
2 The flight was late because of the bad wea___.
3 He answered all the questions corr___.
4 Scientists made an important disc___ last year.
5 We all need to red___ the amount of plastic we use.
6 Most children enjoy pla___ outside after school.
Choose the word that standard English uses with the other words. Several of these test the Indian English habits in the Exam Trap above.
1 I am sorry, I ______ a mistake in my email.
2 We have studied for two hours. Can we ______ a break?
3 In the meeting, we discussed ______ new timetable.
4 My sister is very good ______ mathematics.
5 Please ______ your homework before Friday.
6 The bus was late because of ______ traffic in the city centre.
What it tests: whether you can use grammar, vocabulary and meaning together to rebuild a whole paragraph. You see a short paragraph (from a story, a news report or a textbook). Several words in it are unfinished: the second half of each word is missing, and you type it. You have 3 minutes for the paragraph, and you meet this task 3–6 times. Each word is marked separately, and the spelling must be correct.
Duolingo's guide gives four rules that help you:
| Rule | How it helps you |
|---|---|
| The title and the first and last sentences are complete. | Read them first: they tell you the topic and how the paragraph ends. |
| Unfinished words are never next to each other. | There is always at least one complete word on each side of a gap to give you a clue. |
| Names and abbreviations are never unfinished. | Every gap is an ordinary English word. |
| Each word is marked on its own. | One difficult word costs one mark, not the paragraph. Move on and come back. |
Here is a short paragraph as it might look (each _ is one missing letter):
Libraries are changing fast. Today, ma__ libraries le__ laptops a__ cameras as we__ as books. So__ also of___ free classes in coding and languages. People still come to libraries to read, study and meet friends.
Answers: many, lend, and, well, Some, offer. Notice how often a word is decided by grammar: a__ between two nouns is and; we__ in as … as books completes the phrase as well as; of___ after also needs a plural verb to match Some (libraries): offer, not offers.
the · and · of · to · in · is · are · was · were · for · that · with · from · their · they · this · because · when · many · some. Learn to see them from their first letter or two: th___ before a noun is often their; bec____ before a reason is because.
Exam conditions: 3 minutes. Complete the 9 unfinished words. Write the full words, numbered 1–9 in order.
In many towns, the busiest place on a Saturday morning is the open-air market. Farmers arr___ before sunrise to s__ up their stalls. They br___ fresh fruit, veget_____ and eggs fr__ nearby villages. Many shop____ prefer these markets bec____ the food is fr___ and the prices are often lo___. By noon, most of the stalls are empty and the farmers are on their way home.
Exam conditions: 3 minutes. Complete the 8 unfinished words. Write the full words, numbered 1–8 in order. This paragraph is a story, so watch for past tense endings.
Ravi had just finished a long day at the library when he noticed that his room key was missing. He che____ every pocket in h__ jacket, but it was n__ there. Then he remem_____ that he had put it o_ a desk while he opened his bag. He wal___ back to the library as fa__ as he could. The libr_____ at the front desk held up a small silver key. "Is this yours?" she asked, and Ravi laughed with relief.
In Read and Complete and Fill in the Blanks you type the letters yourself, so a spelling mistake is a wrong answer. These are words FLC teachers often see misspelt. Choose the correct spelling.
1 Keep your notes for each subject in a ______ folder.
2 The story is exciting from the ______ to the end.
3 The accident ______ late at night.
4 The shop is open ______ nine o'clock.
5 Please write your email ______ clearly on the form.
6 We will meet again ______ morning.
What it tests: whether you can follow a longer text from start to finish: its words, how its sentences connect, its details and its main idea. You get 2–3 sets in a test. Each set is one passage with six questions, shown one at a time, and you have 7 or 8 minutes for all six together. Across your sets there is at least one story (narrative) and one information text (expository).
The six questions always come in this order, and the passage grows as you go:
| Order | Question | What you see and do | How it is marked |
|---|---|---|---|
| 1 | Complete the Sentences | the first half of the passage with 3–10 missing words; choose a word for each blank from the choices | each blank right or wrong |
| 2 | Complete the Passage | the second half appears, with one sentence missing between the halves; choose the sentence that joins them | right or wrong |
| 3 and 4 | Highlight the Answer (two questions) | the full passage and a question; drag with the mouse to highlight the words that answer it | partial credit; most credit for an exact highlight |
| 5 | Identify the Idea | the full passage; choose its main idea from a few options | right or wrong |
| 6 | Title the Passage | the full passage; choose the best title from a few options | right or wrong |
Order, timing and marking are from the DET Question Guide 2026. Everyone gets at least one 8-minute set.
There is one clock for the whole set, so plan your minutes:
| Question | FLC time aim (8-minute set) | FLC time aim (7-minute set) |
|---|---|---|
| Complete the Sentences | about 2½ minutes | about 2 minutes |
| Complete the Passage | about 1½ minutes | about 1½ minutes |
| Highlight the Answer (×2) | about 1 minute each | about 1 minute each |
| Identify the Idea and Title | about 1 minute together, with a little spare | about 1 minute together |
These are FLC planning aims, not Duolingo rules.
Each question shows you more of the same text. By the time you reach Identify the Idea, you have read the passage twice and worked with its details. Do not start again from zero: your answers to the first four questions are your notes for the last two. Your choice for Identify the Idea also helps you choose the title.
Choose the best answer.
1 Which question comes first in every Interactive Reading set?
2 How many Highlight the Answer questions are there in one set?
3 Which Interactive Reading question gives partial credit?
4 In Complete the Sentences, you get four blanks right and one wrong. How is it marked?
5 How long do you have for one Interactive Reading set?
You see the first half of the passage with 3–10 words missing. For each blank you choose a word from a short list. The text stays on the screen while you choose. Each blank is marked separately, so every blank is worth trying. The choices for one blank are often the same word in different forms (leave, leaves, left, leaving), or small linking words (because, although, unless), so grammar decides many of them.
Now the second half of the passage appears, and one sentence is missing between the two halves. You choose the sentence that joins them. The right sentence must fit both the sentence before the gap and the sentence after it. On the test you can see how each choice looks in the gap before you decide.
Sam wanted to surprise his parents by cooking dinner. He found a recipe online and bought everything he needed. [gap] When his parents came home, they found him opening the windows and holding a very black pan.
Choices: A) The meal was perfect, and everyone enjoyed it. B) But while he was talking on the phone, the rice burnt. C) His parents often cooked pasta on Sundays. D) He decided to go to a restaurant instead.
Answer: B. The sentence after the gap shows a problem (open windows, a black pan), so the missing sentence must explain how something went wrong. A is the opposite of what follows. C is off the topic: it does not join the two parts. D contradicts the end, where Sam is clearly at home with a pan. Notice the linking word But in B: it signals the change from plan to problem.
Contrast: but, however, although, instead. Reason: because, since, this is because. Result: so, as a result, therefore. Time in a story: then, later, suddenly, after that. Adding: also, in addition. When a choice starts with one of these, check that the relationship is really there in the text.
Exam conditions: about 2½ minutes. Choose the best word for each numbered blank.
In some cities, people have started putting shared fridges on the street. Anyone can 1 food in the fridge, and anyone who needs food can take it. The idea is simple: food that would 2 be thrown away goes to people who can use it. Most fridges are looked after by 3 who clean them and check that the food is still safe to eat. Cafés and bakeries 4 give their unsold bread and cakes at the end of the day. 5 the fridges are open day and night, people can visit 6 it suits them.

Exam conditions: about 1½ minutes each. Choose the sentence that best joins the two parts.
Maya had practised her presentation every evening for a week. On the morning of the class, she woke up with a sore throat and almost no voice. [gap] Her teacher agreed, and Maya gave her talk the following Monday, feeling much better.
1 Which sentence fills the gap?
Honey can last for a very long time. Archaeologists have found honey thousands of years old in ancient tombs, and it was still safe to eat. [gap] Bacteria need water to grow, so they cannot survive in honey.
2 Which sentence fills the gap?
When the first bicycles appeared in the early 1800s, they had no pedals. [gap] Pedals were added later, which made bicycles faster and much easier to ride.
3 Which sentence fills the gap?
Now you see the whole passage, with the missing sentence filled in, and a question. You click and drag with the mouse to highlight the part of the text that answers the question. You do not need to highlight a full sentence. The answer is always in the text, word for word. This question gives partial credit: you get the most credit when your highlight is exactly right, and some credit when it is close. There are two of these questions in every set.
Every morning, the children of Kalo Island travel to school by boat. The island has only two hundred people and no secondary school, so older students cross the bay to the town of Port Ellis.
Question: Where do the older students go to school?
| Highlight | Result |
|---|---|
| the town of Port Ellis | Best. It answers "where" exactly, with nothing extra. |
| Port Ellis | Also acceptable: the place name alone answers the question. |
| so older students cross the bay to the town of Port Ellis | Too long: it includes the reason and the journey, which the question did not ask for. Less credit. |
| cross the bay | Wrong part: it describes the journey, not the place. |
Many students highlight the whole sentence "to be safe". On the DET this is not safe: extra words lower your credit. Match the question word: where wants a place, when a time, who a person, why a reason (often after because or so), what … do an action. Practise dragging with the mouse or trackpad you will use on test day, so the highlight starts and stops on the right word.
Exam conditions: about 1 minute per question. For each question, write the exact words from the passage that you would highlight. Keep your answer as short as possible.
Every morning, the children of Kalo Island travel to school by boat. The island has only two hundred people and no secondary school, so older students cross the bay to the town of Port Ellis. The trip takes about twenty minutes when the sea is calm. In winter, strong winds sometimes stop the boat, and on those days the students join their lessons online from the island's community hall. Last year, the town council bought a larger boat with a covered deck, so the students now stay dry even when it rains. Many parents say the daily journey has taught their children to be independent and to plan ahead.
The last two questions ask about the whole text. In Identify the Idea you choose the sentence that says what the whole passage is about. In Title the Passage you choose the best title. Both are marked right or wrong, and both have a few options. The right answer covers the whole passage: its beginning, middle and end.
The wrong options are written to catch readers in four familiar ways:
| Trap | What it does | How to spot it |
|---|---|---|
| Too narrow | a true detail from one sentence, not the whole text | Ask: is this what the whole passage is about, or one line? |
| Too broad | a big topic much wider than the passage | Could this be the title of a whole book? Then it is too broad. |
| Opposite | says the reverse of the text | Watch not, no, never, difficult/easy, more/less. |
| Not stated | sounds sensible but is not in the text, or is too strong (all, always, must) | Can you point to the line? If not, reject it. |
For The Island School Run passage in Exercise 13, which is the main idea?
A) The island has two hundred people. B) Children on a small island travel to school by boat, which brings difficulties but also benefits. C) Education is important all over the world. D) Strong winds stop the boat every day.
Answer: B. It covers the boat journey, the problems (winter winds) and the benefits (independence). A is too narrow: one detail. C is too broad: the passage is about one island, not the world. D is not stated and too strong: the winds stop the boat sometimes, in winter, not every day.
Questions 1 and 2 are about The Island School Run in Exercise 13. Questions 3 and 4 are about the passage below. Choose the best answer.
1 Which sentence best describes the main idea of The Island School Run?
2 Which is the best title for The Island School Run?
For many years, people believed that goldfish could remember things for only three seconds. Scientists have now tested this idea in several experiments. In one study, goldfish learned to push a small lever to get food. Weeks later, they still remembered how to do it. In another, fish learned that food arrived when a certain sound was played, and they swam to the right place months after the training. These results show that the famous "three-second memory" is a myth: goldfish can remember for much longer than people once thought.
3 Which sentence best describes the main idea of the passage?
4 Which is the best title for the passage?
Each statement is a wrong main idea for the goldfish passage in Exercise 14. Write its trap type: too narrow, too broad, opposite or not stated.
Now put the five lessons together. Each exercise below is a full set in the order of the test. On the test, each question has its own screen and the full passage appears from question 3 onwards. Here, answer the questions in order, and use the parts of the passage printed for each step. Time yourself: 8 minutes for the first set, 7 minutes for the second.
Exam conditions: 8 minutes for the whole set. Questions 1–5: Complete the Sentences. Question 6: Complete the Passage. Highlight questions H1 and H2: write the exact words you would highlight. Questions 7 and 8: Identify the Idea and Title the Passage.
Part 1
When Arjun moved to Toronto for college, he wanted a part-time job 1 he could pay for his books. He applied to many shops, but nobody called him 2. One afternoon, he walked past a small bakery with a sign in the window: "Help wanted, early mornings." He went 3 and spoke to the owner, an older woman named Mrs Costa. She asked him 4 he could start work at five o'clock. Arjun was not a morning person, but he said yes 5 hesitating.

Part 1
A green roof is a roof that is 1 with plants. In cities, where there is little space 2 parks, green roofs can bring nature back to buildings. The plants grow in a thin layer of soil 3 sits on top of a waterproof layer. This keeps rainwater 4 entering the building. Green roofs are 5 common in parts of Europe, and more cities around the world are now adding them.

Part 2 (the second half, with one sentence missing at the start)
[gap] In summer, the plants and soil keep the building cooler, so less energy is needed for air conditioning. They also hold rainwater, which reduces flooding in the streets after heavy storms. However, green roofs cost more to build than ordinary roofs, and the building must be strong enough to carry the extra weight.

Every Reading question has its own clock, and the clock does not stop. Here is how FLC asks Foundation students to use each one:
| Question | Clock | FLC aim at Level 1 |
|---|---|---|
| Read and Select | 5 seconds per word | decide within about 3 seconds; never let it reach zero |
| Fill in the Blanks | 20 seconds | type by about 15 seconds; use the rest to check spelling |
| Read and Complete | 3 minutes | easy words in the first 1½ minutes; harder words next; 20 seconds to fill any gaps |
| Interactive Reading | 7 or 8 minutes per set | follow the plan in Lesson 5; never leave Title the Passage unanswered |
In Read and Complete and Interactive Reading, if one word or question has taken more than about 20 seconds longer than it should, choose or type your best answer and move on. One difficult blank is one mark; the questions after it are worth many more.
Your Reading subscore (10–160, in steps of 5) is reported with Listening, Writing and Speaking. The overall score is the average of the four, rounded up to the next 5. For example, Reading 85, Listening 90, Writing 75 and Speaking 80 give an average of 82.5, which rounds up to an overall score of 85. Your Reading score also counts in two combined subscores: Comprehension (Reading and Listening) and Literacy (Reading and Writing).
| DET score | CEFR | About IELTS |
|---|---|---|
| 60 | B1 | 4 |
| 65–75 | B1 | 4.5 |
| 80–90 | B1 | 5 |
| 95–100 | B1 (95) to B2 (100) | 5.5 |
From the DET Scoring Guide 2026 concordance. These links are approximate, and universities set their own requirements.

1 In Read and Select, a word appears that you have never seen, and you cannot find any real parts in it. One second is left. What should you do?
2 You have spent 40 seconds on one hard word in Read and Complete. What is the best action?
3 A student scores Reading 85, Listening 90, Writing 75 and Speaking 80. What is the overall score?
4 Which combined subscore is made from Reading and Writing?
5 In Highlight the Answer, a student highlights a whole paragraph "to be safe". What happens?
6 With 30 seconds left in an Interactive Reading set, you reach Title the Passage. What should you do?
These are the habits FLC teachers see most often in Foundation students from Gujarat, Punjab and across India. Each one costs real marks, and each one is easy to fix.
| Habit | What it costs | The fix |
|---|---|---|
| Clicking Yes in Read and Select because a word "looks familiar" (garbon, freind) | fake words marked as real | Check the word letter by letter against the word you know. |
| Freezing on a Read and Select word until the 5 seconds run out | a certain wrong answer | Decide in about 3 seconds; if you have never seen it, click No. |
| Typing words the way they sound (seperate, untill, occured, tommorow) | words you already understood | Keep a list of your own spelling mistakes and test yourself weekly. |
| Relying on phone autocorrect | spelling marks; the test has no spell check | Practise typing on a laptop keyboard with spell check turned off. |
| Using Indian English partners (do a mistake, discuss about, cope up with) | Fill in the Blanks and Complete the Sentences items | Learn the standard partner: make a mistake, discuss something, cope with. |
| Forgetting endings: -s, -ed, -ing, -ly | easy grammar items | After each word, check: singular or plural? past or present? adjective or adverb? |
| Translating every sentence into Gujarati, Punjabi or Hindi | time: the last Interactive Reading questions are guessed or missed | Read for meaning in English; look only for the line you need. |
| Highlighting whole sentences | partial credit lost | Highlight only the words that answer the question. |
| Choosing a title that matches one striking detail | "too narrow" traps | Say the whole passage in one sentence first, then choose. |
The DET is taken at home, but it is not relaxed. Practise on the same computer, keyboard and mouse you will use on test day. Students who prepare only on a phone often type slowly on a laptop, struggle to drag a clean highlight on a trackpad, and lose seconds on every Reading question. Check Duolingo's current technical and room requirements well before your test date.
Read something short in English every day: a news story for young readers, a university's student blog, a short story. Copy five new words into your notebook with their exact spelling, and say them aloud. Each week, ask a friend to test you on that week's words with their spelling. Twenty minutes a day for a month builds the vocabulary that Read and Select and Read and Complete reward.
| Week | Focus | Daily work (about 30 minutes) |
|---|---|---|
| 1 | Format, Read and Select | Lessons 1–2. Learn ten new words a day with their spelling. Make a list of word parts (un-, dis-, -ness, -ful) and three real words for each. |
| 2 | Fill in the Blanks and Read and Complete | Lessons 3–4. Ten Fill in the Blanks sentences and one Read and Complete paragraph a day, timed. Say the kind of word before you type. |
| 3 | Interactive Reading | Lessons 5–8. One passage a day: one question type at a time, then all six together. |
| 4 | Timing and review | Lessons 9–10. Two full timed sets this week. Fill in your error log and repeat the lesson behind your biggest loss. |
