I took the Hesi a couple months ago and did pretty well (89%).
There are different versions of the Hesi A2 exam. Some schools need you to take all of the sections (math, reading, grammar, anatomy&physiology, chemistry, vocabulary, biology and physics) my school only required the first 6. some schools only require 4 of those categories. different schools pick different categories.
The Evolve Reach Admission Assessment Exam Review (2nd ed) was the book we were told to study from. It helped a lot for math, somewhat for chem/reading/grammar/vocab, and but not much for anatomy & physiology (the questions were easy, but very random, look over your notes instead to study for that).
The test is not hard. I am horrible at math, hate math, and got a 94% on that section. you just need to study and make sure you know how to solve the problems in the study guide. Vocab is where most people struggle, because there are words on the test that you will just not know and will have to guess. Chem is very basic, like middle school level. Study and you will do fine.
I am transferring to another school for nursing because mine has become far too competitive. My friend got a 93% on her test and has a 3.79 gpa and did not get in. We both are going to take the TEAS. Could you tell me a bit about it? What does the science consist of/ how many categories are there/ what was most difficult/ how to study, ect, please
