I just took the Hesi today. I took me 3.5 hours and my school requires all sections except physics. My score was an 83. I studied using the Hesi Admission Study Guide. The book prepared me well for english, vocabulary, and math. I made above 90% in those areas. I made 84 on reading comprehension which was great for me because I always do horrible in that section on standardized tests. Now, the sciences are another story. I did ok in A&P I got 88%, biology was 76, Chemistry I made 68 . The book in no way prepared me for the sciences. I relied on the things I rememberd in class. I Haven't taken Chemistry yet. Just study your book for math. It is basically fractions, percentages, ratios, and converting. I didn't have any roman numerals or temperature conversions. Also study quizlets for the vocabulary. I saw at least 75% of the words I saw on quizlets. Some are just common sense. Anyways I'm happy with my grade. Passing is basically 70% at my school and if you get above 80% you get 10 bonus points added to your quality school for admission ranking purposes.
