Many students applying to study medicine are extremely worried about the UCAT test, it is utterly alien in the way it is taken, the content which it contains and the immense time pressures which the test involves. The best advice you can receive about this test is to prepare. Do as much practice as you can as the more experience you can get for the test, the better you will do. As someone who took the test twice I can assure you there are no shortcuts, it is entirely dependent on putting in consistent work over a timeframe of several months. Medify is a good resource to use as is Kaplan. Don't bother paying for courses though, they are usually overly expensive and it is much more useful to practice, the advice many provide are available with online resources and you shouldn't waste your money or time. The main way people slip up is by panicking in the testing environment, in order to avoid this you should make yourself familiar with the test format and environment - try taking a driving theory test before you do the UCAT as they are often taken in the same places and having a familiarity with the environment may help you to remain calm in such a stressful situation. Practice a lot, remain calm and don't get discouraged if you feel like you are making little progress in preparation.
