Just wanted to post some useful information regarding the Kaplan pre-entrance exam because it was difficult to find information. The HESI and Teas have been around much longer and the Kaplan is fairly new, comparatively. The test is comprised of 4 parts: Reading Comprehension, Math, Writing, and Science in that order. It is approximately 3 hours and 91 questions. The reading comp section utilizes a split screen on your monitor, which is very helpful. You read four passages, I believe, and answer a few questions about each. There is a calculator window you can use during the math section. The Kaplan-published book for nursing entrance exams was almost useless. The reading comprehension section was similar, but that's where it ends because the book is designed to cover every major nursing entrance exam. The other tests cover topics such as chemistry, physics, biology, geometry and the Kaplan does not. I used a basic math book for nurses to review and that's all that is needed. The math section is fractions, fractions and more fractions (adding, multiplying, converting - you get the picture) decimals, addition, percentages and word problems that weren't very scary. I am terrible at math and scored an A on that section because it was basic and I practiced for a few hours. The writing section was harder than we thought. There is subject-verb agreement, which isn't difficult, but questions like "after which sentence should this topic be introduced" left us feeling like more than one answer seemed correct. I missed more than I thought I would! The science section is ONLY physiology, and some pretty specific physiology questions at that. I have not taken A&P II and it was by far my lowest score...a 60. My overall score was 84% and my critical thinking score was 94% and those are the two scores my school uses when reviewing scores. For the science section, I would recommend reviewing your A&P notes on the systems Kaplan lists and/or purchasing the A&P Cliffs Notes book. However, the questions were difficult and the book couldn't have prepared me the way A&P II would have. All in all, I didn't find the Kaplan to be as difficult as I worried it would be.
