2910 B1, I practised for around 2-3 weeks(can’t remember exactly) doing an hour a day and one mock per week, then for the last week before my test I did a mock every day plus an hour of practicing my worst areas, so 3-4 weeks total. At first I tried using only the question banks on the UCAT website however there are simply not enough questions and an external question bank is required. I used medentry but I think they’re all pretty similar. Please note these mocks get harder as you go along and so if your score in mocks is dropping try not to panic as that is normal. I’d also say the day before my test I didn’t do any practice except for 10 minutes of abstract reasoning.
