The LNAT is the national university admissions test which assesses the aptitude of prospective Law students. Not all universities require Law applicants to take this test, but the best Law schools do, so it is well worth checking which universities do and don't expect you to sit the LNAT. If you are required to take the LNAT as part of your application, all you need to do is register online and attend your allocated timeslot. The test itself is comprised of two parts: part A and part B. Part A is a comprehension-focused exercise which requires you to read 12 passages and answer 3 or 4 multiple-choice questions on its contents. Part B consists of 3 essay questions, of which you must answer one. In terms of preparation, practice makes perfect! When I was studying for my LNAT, I made use of a practice book designed for students, which contained a multitude of sample questions and answers. There are also a few past papers available on the LNAT website, which are well worth printing off and working through. In terms of the essay section, it is slightly harder to prepare for as any topic could come up, but it is worth concentrating on your essay-writing skills and writing practice essays as much as possible.
