Hii,
This is my personal opinion btw. I have basically the same stats as you and am applying for Cambridge, Bristol, Imperial and HYMS. I chose HYMS as my safer option, however, due to your UCAT Bristol is also almost a guaranteed interview (unless the cut off is crazy high this yr). Although it is quite a risky choice you have gone for I don’t think it’s insane considering your stats. If you are doubting it I would look for other unis where the Interview isn’t the entire deciding choice for an offer such as Newcastle!
If not I would really practice with your interview skills as the competitions that stage for the schools you have picked will be extremely intense (that is what I’m aiming to do to make sure I don’t fall at the final hurdle)
Idk how much this helped. Can I ask which college in Cambridge you are applying to and why (I struggled to decide so like to know other people’s reasons)
