WELCOME TO KAPLAN!

Today you begin your Kaplan MCAT preparation with a full “work-up” that includes a Personal Profileand two Diagnostic Tests to evaluate both your science knowledge and your critical thinking ability.Please note that in order to maintain your Higher Score Guarantee eligibility you must take the online (non PDF)version of the diagnostic found on your Kaptest.com student syllabus. From the information obtained here, we will prescribe a personalized study regimen designed to review and reinforce relevant science content as well as emphasize the “higher order” analytical thinking and problem-solving skills the MCAT is designed to test.

The Science Diagnostic Test consists of 120 discrete science questions, 30 each in biology, generalchemistry, organic chemistry, and physics. You will do this test first. The test is specifically designed toassess your raw knowledge in the science areas covered on the MCAT. The results of this test, incombination with the MCAT Diagnostic and the Personal Profile, will provide a more complete picture ofyour “MCAT health.” Please use the section of your Online Student Center labeled Science Diagnostic tocomplete this test.

The Personal Profile contains questions about your academic background, study habits, perceivedacademic strengths and weaknesses, etc. Your responses to these questions will be integrated with yourperformance on the Diagnostic Tests, enabling us to tailor a study plan suited to your study habits andacademic needs. PLEASE ANSWER EVERY QUESTION (UNLESS YOU ARE TOLD TO LEAVE ITBLANK), or incomplete feedback will be generated. You can input your Personal Profile answers into thelast section of the Science Diagnostic input form,(see above for the location of this form) in a sectionlabeled Personal Profile.

The MCAT Diagnostic Test (half-length) simulates the actual MCAT experience. The test will indicatehow well, at present, you can handle MCAT-style questions and passages that require critical thinking andproblem-solving. Remember, the MCAT is not just a science exam. While it requires you to have a firmknowledge of fundamental science concepts, it also tests your ability to integrate new information presentedin challenging science passages. As on the actual MCAT, there is no penalty for incorrect answers. Pleaseuse the input form labeled MCAT Diagnostic to input your responses to this test.

Remember, your feedback from today’s “work-up” is only a baseline evaluation. The Kaplan MCATProgram is designed to help you master ALL the material and skills necessary for your success on theMCAT.

Good luck!
