I did the UMAT this year, with the idea that I wanted to enter undergraduate medicine. I used medentry, and did all the practice exams and most of the drills. Then, like 2 weeks after doing it, I wasn't so sure about my interest in medicine anymore. I didn't think I was mature enough to dissect cadavers and look at anatomy. The thought of it actually made me a little queasy. Also, I'd heard that 1st year med is much tougher than year 12. As a result, I started to question my suitability for medicine. This is a bit annoying, since now I don't really know what I want to do anymore.
Boring life story aside, I consistently found that:
* S3 was my best section. I wouldn't only do drills/exams on medentry for S3. I'd also try to find patterns in everyday life (there are a lot of patterns you can discover in chemistry if you try lol).
* S2 was my next best section. This one was weird. My scores on medentry would fluctuate a lot. I found I did better if I did not practice heaps at this section, because I decided it was a 'spur of the moment' kind of thing. That said, I looked at the body language of my friends a lot, of my family. I tried to see how people operated (which is a bit creepy I know). I also brushed up on my emotional vocab, and am glad I did, because there was not one word I did not know the meaning of in the exam.
* S1 was not my best section. But with S1 questions, never give up. Keep trying, even if that one question takes you 45min. Exhaust all your options. With the logical reasoning part that has short passages, make sure you read these carefully and try to understand them.
