I didn't. Didn't have enough time or money lol. I think it'll only probably help you with the timing. As far as the material goes, I think it's either you know it or you don't. That's just my opinion. If you don't have time, really, just focus on the fundamentals. Especially for Chem and Orgo! PR had 2 sample exams at the end of the book which I found really helpful. Nothing extremely difficult (like the DAT). Hope that helped. GL with your exam!
