The following information about LNAT Results is taken from The Ultimate LNAT Guide: 400 Practice Questions

Booking your Test

If you’re applying to Oxford, it’s necessary to take the test before the 20th October. It makes no difference what day you take it on as the results of all test results taken between the 1st September and 20th October are only sent to universities on the 21st October. That said, it would be best not to leave it too late in case of unforeseen circumstances, such as illness.
For all other universities, you just need to take the test before the 20th January. While it would be preferable not to leave it to the last minute, it is not necessary to do it in September or even before the 20th October. It would be much better to ensure that you’re comfortable with the LNAT and have completed as much practice as possible. This would stand you in good stead for a solid LNAT result.

Improve your Timing

Whilst this isn’t completely true, it illustrates a very important point. Once you’ve practiced and know how to answer the questions, the clock is your biggest enemy. This seemingly obvious statement has one very important consequence. The way to improve your LNAT score is to improve your speed. There is no magic bullet. But there are a great number of techniques that, with practice, will give you significant time gains, allowing you to answer more questions and score more marks.

Using your LNAT Score

The weighting which the universities place on the LNAT varies. The University of Bristol, for example, place a 25% weighting on it. The universities use the LNAT for a reason and place a lot of importance on both Section A and B. Therefore, the better you do at the LNAT, the better your chances of securing an offer. Given how competitive the law admissions process is, it is vital to produce a solid score on the LNAT. Each university will offer its own guidance on the LNAT on their admissions website.
