Ucat revision

can i cram my ucat revision a week before the actual exam or is it impossible

Depending on how good you are at problem-solving already, it is possible. You should make sure to focus on your weaker areas and also your timing as that can be one of the hardest parts (probably don't do as much on SJT as most unis don't really care about it as long as you're above band 4). Also, do a lot of practice questions/papers. I believe most people tend to spend 1 month+ on revision. I spent a bit less time and still got a pretty good score tho. It is unlikely that you will get a great score only revising for a week, you may still do well, but even if your score isn't what you want, you could always consider the BMAT (which I kinda crammed for tbh). Good luck with your UCAT, I hope it goes well (Make sure you answer every question)
