LNAT vs UCAT: the basics

The LNAT vs UCAT question comes up a lot because both are admissions tests used by top UK universities – but they are for completely different subjects. The LNAT is for law. The UCAT is for medicine and dentistry. If you are applying for law, you only need the LNAT. If you are applying for medicine, you only need the UCAT. Very few students need both.

What each test actually measures

The LNAT

The LNAT tests critical reading and argumentative writing. Section A has 42 multiple choice questions based on 5 reading passages. You need to read dense, analytical texts and answer questions based purely on what the text says – not your general knowledge. Section B is a 40-minute essay in which you argue a position on a given question.

The UCAT

The UCAT tests a broader range of cognitive abilities across five sections: verbal reasoning, decision making, quantitative reasoning, abstract reasoning, and situational judgement. It is computer-adaptive and includes a significant numerical element.

Which is harder?

This depends entirely on your strengths. Students who are strong readers and writers tend to find the LNAT more manageable. Students who are strong in maths and abstract thinking tend to find the UCAT more manageable.

Objectively, the LNAT has a narrower skill set – it is almost entirely about reading comprehension and argument analysis. The UCAT covers more ground and requires more varied preparation.

Can you prepare for both at the same time?

If you are genuinely considering both law and medicine (which is unusual but does happen), you would need to sit both. The preparation is quite different – LNAT preparation focuses on reading quality and argumentative writing, while UCAT preparation requires more mechanical practice across five distinct question types.

If you are a law applicant, focus entirely on the LNAT. Start with our free LNAT practice paper and build from there with full-length LNAT practice tests.
