questions r ur best bet to practice for ucat.
I don't think books or non online practice is the best for ucat, u will be able to read strategies and stuff (which is important) but the best way to improve on ucat is practice bcos it is a skills test. The feeling and pressure of doing a computer test is very different to a physical one. e.g. for QR u need to be able to use the online calculator efficiently.
I didnt go to a prep course but i used questions on medentry and it was pretty good
I'm doing ucatmasterclass - they have the online course and online exams to practice on their simulator. I think it's all about knowing the strategies and then testing yourself with the computer test. They have interview tips based on the aus unis so I think a good all rounder - also quite affordable.
