I worked hard for my A's in Anatomy class, but the first time i took the hesi, i scored a 64! The questions are very precise and over everything...for the anatomy portion, the elsevier book didnt help much. I used my school notes and dedicated hours to studying...the second time i got a 94! :) i recommend the test-guide.com practice tests and the mc graw-hill practice tests (from barnes and noble). my second time around, i got a cummulative score of a 96% :) Practice makes perfect, good luck!!
