Are you asking about the HESI? It made me more nervous than it should have. The Chemistry section was the hardest for me but I haven't taken Chemistry in 20 years. I used NurseHub to study and I believe it helped me overall. For math ideas, I used mathisfun.com to brush up on fractions, decimals and ratios. I got a 91 overall composite score, which made me and my admission rep very happy ?
