The following BMAT preparation advice is taken from The Ultimate BMAT Guide: 600 Practice Questions
It is much easier to prepare for the BMAT if you practice little and often. Start your BMAT preparation well in advance; ideally by mid-September but at the latest by early October. This way you will have plenty of time to complete as many papers as you wish to feel comfortable and won’t have to panic and cram just before the test, which is a much less effective and more stressful way to learn. In general, an early start will give you the opportunity to identify the complex issues and work at your own pace.
It is essential that you don’t get stuck with the hardest questions – no doubt there will be some. In the time spent answering only one of these, you may miss out on answering three easier questions. If a question is taking too long, choose a sensible answer and move on. Never see this as giving up or in any way failing, rather it is the smart way to approach a test with a tight time limit. With practice and discipline, you can get very good at this and learn to maximise your efficiency. It is not about being a hero and aiming for full marks – this is almost impossible and very much unnecessary (even Oxbridge will regard any score higher than 7 as exceptional). Whilst this might seem like obvious advice – it is extremely important for your BMAT Preparation(arguably the most important!).
Some questions in sections 1 + 2 can be long and complex – and given the intense time pressure, you need to know your limits. It is essential that you don’t get stuck with very difficult questions. If a question looks particularly long or complex, move on and mark it for review. You don’t want to be caught 5 questions short at the end just because you took more than 3 minutes in answering a challenging multi-step physics question. If a question is taking too long, choose a sensible answer and move on. Remember that each question carries equal weighting and therefore, you should adjust your timing in accordingly. With practice and discipline, you can get very good at this. This will in turn also maximise your BMAT preparation efficiency.
