Hey! I watched my cousin take the ucat last year and looking at the questions, I freaked outt. I’m in the same place as you and her now.
I would say that 12 weeks is too early, especially with the UCAT having less content. Obviously that doesn’t mean you shouldn’t revise hard enough- it’s still a really difficult exam. It’s recommended to only revise 6-8 weeks and roughly 60-80 hours MAX. I don’t want you to risk burning out. Focus on school for the next few weeks until summer holidays, have a little break and then ease into revising consistently.
Also another thing- the exam is on a computer. The book may be helpful with having more questions and I think it actually explains them pretty well (if you have the ucat 1250/1300 book) but I realllyy recommend practicing online on a computer to know what it’ll be like for the real thing (you can check the official ucat website for this). Maybe look into purchasing a subscription for the one of the popular question bank websites?
I would recommend making a timetable so like the first two weeks you understand each section and do untimed questions to grasp what it’s like, in week 3-4 increase the frequency of qs so you’re doing 100-200 a day and then 5+ continue with questions but time them and be strict! In the last week before your exam, do some of the mocks- there’s some on the offices website too.
Good luck, I hope you get a really good score and get into whatever course and uni you’re thinking of applying to! (Pray for me too pls lol)
