I looked to this website for tips on passing the HESI A2, and since it had been a while since someone posted their success story, I thought I would post mine. I scored 88.8% overall. This may not be above 90%, but I still think its pretty good! Here are the sources I used while studying: The Elsevier study guide McGraw Hill practice tests Quizlet Cliff Notes If you are like me, you typically over prepare for important tests. I am notorious for doing this, but I say better be safe than sorry! I spent about 2-3 months studying for the exam. I spent about 1-2 hours a day between work, school and social life. I spent more time in the weeks leading up to the exam, and took the McGraw Hill practice exams two weeks before the exam to make sure I was ready. Here are my scores: Vocabulary I scored a 84%- I did so by studying the Elsevier book words, and also used quizlet and the two links I posted above. Reading Comprehension: 86%- I used the Elsevier book, as well as the McGraw practice tests. Math- 82%- This was my worst score. All I have to say is pay close attention to directions! I used the Elsevier book, as well as the links, and quizlet to quiz myself on conversions and roman numerals. Anatomy- 100%- I did very well in A&P 1 and 2, but I refreshed myself on terms by using mainly cliff notes, as well as Elsevier, McGraw Hill, the links, and quizlet. Grammar- 92%- I mostly used the Elsevier book to study this one. I hope some of these suggestions help you to pass your HESI A2!
