As you all know some schools require that you take the HESI a2 before entering the nursing program. My first question regards the study guide. I bought the Admission Assesment Review 2nd edition for HESi and was wondering if it'll be any help. Second can anybody who has taken the HESI a2 give me any tips as to what to expect in the Anatomy & Physiology part. (what to study, any specific bodily system, etc etc) Thank you so much for your time guys and girls. Tinh Lai.
