The other posts are correct. The HESI is a standardized exam meant to give to school an indication of how well you would do on the NCLEX. However, in our school, the HESI is used as our final exam for each nursing course (Foundations, Med-Surg, Psych, OB, etc) and is worth 30% of our grade. Then, for our final semester we have to take the comprehensive exit HESI which determines if we will graduate with our BSN or not.
