I will be taking my HESI entrance exam next summer or fall at Edison State college. I went to my local bookstore to see if they had the HESI admission exam study guide, which they did not have, so I got "the complete idiots guide to nursing entrance exams" if focuses on multiple types of exams, which includes HESI A2... my question is is HESI and HESI A2 the same, similiar or completely different? Also, has anybody used this book as a study guide? was is helpful? It has practice tests on multiple subjects. I have 2 babies under 2 so I thought it would be good to start studying WAY in advance to get the best possible score the first time. thank you!
