We take the Hesi at my nursing school, and I have found that med pubs makes a review book that is similar to the Hesi review book, only written in more simple terms. I think that this book is amazing and I have used it for 4 Hesi exams now. Just remember to relax the night before the test, and be calm during the exam. Also, I found that a dab of lavander extract on my wrist helps. When I feel that i am getting nervous during the test I smell my wrist and it calms me.
