BMAT and UCAT books Watch
Don’t know how you define well - I got a 695 average. Definitely use Medify, this is what an overwhelming majority use to study for the UCAT. To be honest with you that’s all you really need but I suppose it wouldn’t hurt to use the ISC books too. Use the official Q banks and mock tests on UCAT consortium website, Medify makes VR easier than the real test. (Btw medify is an online resource with hundreds of questions with solutions and mock tests - it’s the best resource I used for sure)
If not though, the ISC books for both are very good and medify is quite good for UCAT.
