Studying for the HESI Entrance Exam, HELP!!

[ash4560]

I'm taking the HESI entrance exam this Saturday. I've been studying a lot lately but the review book my school made us purchase doesn't seem to prepare you enough for the anatomy and physiology part of the test. I've also been reading that its the hardest part of the test. It's hard to weed out the stuff you wont need and focus on the parts that you will be tested on because its such a broad subject. I was wondering if you guys had any tips on what I should focus on as far as anatomy and physiology goes.

Tips for chemistry and biology would be greatly appreciated also :) ...Thanks in advance!!!
