7 LNAT Mistakes That Cost Students Marks (And How to Avoid Them)

Why knowing the LNAT mistakes to avoid matters

Most of the marks lost in the LNAT are lost to a small set of recurring mistakes. These are not random errors – they are predictable patterns that come up again and again because the LNAT is specifically designed to test whether you can avoid them. Understanding the LNAT mistakes to avoid before you sit the exam is one of the most efficient ways to improve your score.

Mistake 1: Answering from general knowledge instead of the passage

This is the single most common and costly mistake in the LNAT. Students read a passage about a topic they know something about and then answer questions based on what they know rather than what the passage says. The LNAT is testing your ability to analyse the specific argument in front of you – not your general knowledge of the topic.

The fix: Before confirming any answer, ask yourself “where in the passage does it say this?” If you cannot point to a specific part of the text, the answer is probably wrong.

Mistake 2: Spending too long on difficult questions

Students who get stuck on a hard question and spend four or five minutes on it often run out of time in the final passages. The LNAT has 42 questions in 95 minutes. Every question is worth the same mark. A question you cannot answer in two minutes is no more valuable than one you can answer in thirty seconds.

The fix: If a question is taking too long, make your best guess, flag it mentally, and move on. If you finish the section early, return to it. Most students do not finish early, which makes managing time on difficult questions critical.

Mistake 3: Re-reading passages multiple times

Some students read a passage, then re-read it fully for each question. This is a serious time drain. Students who read each passage once carefully and then use targeted re-reading for specific questions consistently outperform those who read the same passage four or five times.

The fix: Read each passage thoroughly once, identify the main argument and structure, then answer questions using targeted re-reading to locate specific information. Do not re-read the whole passage for each question.

Mistake 4: Choosing the most plausible answer rather than the best-supported one

LNAT answer options are carefully constructed so that several seem plausible. The correct answer is the one most directly supported by the passage – not the one that seems most reasonable in general, most likely to be true in the real world, or most interesting.

The fix: For each answer option, test it against the passage directly. The correct answer should be supportable by pointing to specific text. Plausibility without textual support is not enough.

Mistake 5: Ignoring the essay section in preparation

Many students spend all their preparation time on Section A and treat Section B as something they will just write on the day. Section B goes directly to admissions tutors and is assessed as part of your application. A weak essay can undermine an otherwise competitive application.

The fix: Write at least four or five timed practice essays during your preparation. Get feedback from someone who can assess argument quality. Treat Section B with the same seriousness as Section A.

Mistake 6: Preparing only with the official LNAT practice papers

The two official practice papers on the LNAT website are widely considered to be easier than the real exam. Students who prepare only with these papers often find the actual exam significantly harder than expected and are not used to the level of difficulty they encounter.

The fix: Use the official papers to understand the format, but supplement them with practice materials that reflect real exam difficulty. Our free LNAT practice paper and full-length LNAT practice tests are written to match the genuine difficulty of the real exam.

Mistake 7: Leaving preparation too late

The LNAT tests a skill that develops gradually through practice. Students who try to cram in the final week before their test consistently underperform compared to those who prepared steadily over 6-8 weeks. Unlike a knowledge-based exam, you cannot revise your way to a good LNAT score in a short time.

The fix: Start preparation at least 6-8 weeks before your test date. If you are targeting Oxford with a 15th October deadline, this means starting in August as soon as registration opens. Even 3-4 hours of focused practice per week over this period produces significant improvement.
