Hi! I took the HESI earlier this month at BC. I thought the anatomy and physiology portion was easier than I expected (especially since all the info was fresh from the courses!) and the questions were general. The math was somewhat challenging. The questions I had were basically ALL fractions (addition, subtraction, multiplication, division), ratios, and conversions! I didn’t know all of my conversions like pints, quarts, cups, gallons, etc. and you definitely want to memorize those! The other sections weren’t hard. Review the elsevier book. They show you how to do long division again and stuff which is not something I’d waste my time on since you have a calculator. Instead make sure you know things like how you convert mixed numbers to improper fractions, dividing fractions (same change flip), etc. Good luck!
