My class just took hesi this past week. From what i'm hearing, about 33 % didn't pass hesi. I did pretty good (over 900) considering the scores i got after first year hesi (low 600). It's impossible to study for hesi. I had a saunders nclex book and it helped me out, maybe 30%. I did do about 4000 questions out of the saunders CD. What the CD taught me was how to eliminate answers and focus on the 2 most correct answers, and from those 2 to pick one. Hopefully the rest of my classmates can pass on their next try and hopefully nclex boards make more sense than hesi.
