There is no simple strategy to score high in the UKCAT. Each individual student has to develop their own technique and engage with the different subtests in order to do well.
Each section has a set time limit separated by one-minute introductions. You will not be able to carry over any of the time saved in an earlier section. If you find you still have time remaining, it is best to utilise that and have a quick run-through of your answered questions. Once you’ve completed a section, you cannot go back.
Timing is one of the most important factors in the UKCAT. As of now, the most important factor is making yourself familiar with the subtests and developing your own techniques.
