Common CLAT mistakes and how to avoid them

Most candidates who fall short in CLAT did not lack ability. They prepared in ways the exam does not reward, or gave away marks on the day. The mistakes that cost the most, with a fix for each.

CLAT is a reading and reasoning exam with 120 questions in two hours. At the top of the merit list, a few marks separate one NLU from the next. So the mistakes that matter most are rarely about talent. They are about habits: how you read, how you practise, and how you behave in the exam hall.

Below are the mistakes that cost candidates the most, grouped by when they happen, with a fix for each. Read them now, and again a month before the exam.

Mistakes in preparation

1. Starting current affairs late

Current Affairs and GK is about a quarter of the paper, and its questions often go beyond the passage into related facts. Nobody can cover a year of news in the last eight weeks.

Fix: read the news daily from the start of your preparation and make short monthly notes. Revise each month's notes once in the following month.

2. Treating English as "already known"

Many students do well in their first English mock and then stop practising it. Reading comprehension decays without practice, and the section's traps (options that are partly true, or true in the world but not in the passage) catch careless readers.

Fix: two timed passages a day, and a written reason for every answer you check. The English plan for CLAT sets out a routine.

3. Learning law instead of practising principles

Reading law textbooks feels productive. But CLAT gives you the rule in the passage. What it tests is whether you apply that rule exactly.

Fix: spend most legal-reasoning time on passages: read the principle, apply it to the facts, and check your reasoning against the answer key.

4. Ignoring quant

Quantitative Techniques is the smallest section, but ten or more marks at Class 10 level is a lot to give away.

Fix: revise percentages, ratios and averages, and do one data set a day in the last three months.

5. Too few mocks, or mocks without analysis

Taking a mock shows you your score. Analysing it tells you how to improve that score.

Fix: for every mock, spend at least as long on analysis as on the test. Log each wrong answer with its cause. The guide to CLAT mock tests has an analysis template.

Mistakes in reasoning

6. Using outside knowledge against the given principle

This is the most expensive single habit in CLAT. The exam sometimes gives a principle that is simpler than the real law, or that feels unfair. The right answer still follows the principle as given.

Here is an original example.

Principle: A promise to do something for another person, made without receiving anything in return, cannot be enforced in court.

Facts: An aspirant promises a cousin ₹5,000 as a birthday gift. The cousin gets nothing in return and makes no promise. Later the aspirant changes their mind. The cousin sues to recover the ₹5,000.

(a) The cousin will succeed, because a promise must be kept.
(b) The cousin will succeed, because the promise was made to a family member.
(c) The cousin will not succeed, because nothing was given in return for the promise.
(d) The cousin will not succeed, because birthday gifts are never legally binding.

Answer: (c).

  • (a) is a moral view, not the principle.
  • (b) uses outside knowledge. Real contract law has special rules for some promises between close relatives, but the principle here says nothing about family, so you cannot use them.
  • (d) gives the right outcome for the wrong reason, and "never" goes beyond the principle.
  • (c) applies the principle word for word.

7. Choosing the "nearly right" option

Across sections, wrong options are often built to be almost correct. They may be too extreme, cover only part of the passage, or add one word that the passage does not support.

Fix: before marking, point to the line in the passage that supports your answer. If you cannot find one, reconsider.

Mistakes on exam day

8. No fixed section order or time plan

Deciding on the day where to start and how long to spend is a recipe for panic. Without sectional time limits, one difficult section can swallow half an hour.

Fix: fix a section order and a rough time budget in mocks, and stick to it. The guide to time strategy in CLAT explains how to build one.

9. Getting stuck on one passage

A hard passage early in the paper tempts you to keep going until you crack it. Every minute there is a minute taken from easier questions later.

Fix: set yourself a limit, say about eight to nine minutes for a passage with five or six questions. If a passage is not working, mark it, move on and come back.

10. OMR errors

Bubbling in the wrong row, leaving all the bubbling to the last few minutes, or marking two circles in one row all cost marks you actually earned.

Fix: fill the OMR sheet passage by passage or section by section, and check the question number each time you move to a new passage.

What these mistakes cost: a worked example

Suppose two candidates have exactly the same knowledge. Candidate A reaches 100 questions and gets 78 right and 22 wrong. Candidate B makes three of the mistakes above.

Candidate ACandidate B
Questions attempted10092 (lost eight minutes on one passage)
Correct7870
Wrong2222 (includes 4 outside-knowledge errors)
Marks lost to OMR slips02 correct answers marked in the wrong row, so counted wrong
Final correct7868
Final wrong2224
Score78 − 5.5 = 72.568 − 6 = 62

Check the arithmetic: A loses 22 × 0.25 = 5.5, so 78 − 5.5 = 72.5. B's two mis-bubbled answers move from right to wrong, so 70 − 2 = 68 right and 22 + 2 = 24 wrong. B loses 24 × 0.25 = 6, so 68 − 6 = 62.

That is a 10.5-mark gap between two equally able candidates. Near the top of the merit list, that gap can decide which NLU you get, or whether you get one at all.

A self-audit

Answer honestly, yes or no.

QuestionIf the answer is no
Do I read the news every day and keep monthly notes?Start today; revise last month's news this weekend
Do I write a reason for every English and legal answer I review?Begin with your next practice set
Do I analyse every mock for at least as long as I took to write it?Build an error log now
Do I have a fixed section order and time budget?Test two orders over your next four mocks
Do I fill the OMR sheet as I go?Practise with a printed OMR sheet in every mock

What to do next

  • Pick the two mistakes from this list that you make most, and write their fixes on a card.
  • Take your next mock with a fixed order and a passage time limit.
  • Log every wrong answer by cause: reading, principle, knowledge, time or OMR.
  • Read the guide to the last month before CLAT when you are eight weeks out.
