I scored an 86% on the Kaplan and had an overall GPA of 3.82 science GPA was 3.9 my overall points were 92.52 out of 100. I ranked at 15 out of 40. For the Kaplan, know your heart, electrolytes, and neurological systems. A lot of it is common sense. The math is basic. Fractions, decimals, conversions, maybe basic off-algebra. Reading and writing are almost identical to Kaplan prep book. Prep book was not helpful in science you either know it or you don't. You get your score right away. If you get 90 or more points you are in an excellent.position.
