MCAT 2015 Infographic: Critical Analysis and Reasoning

September 22, 2014

We recently created a set on infographics to breakdown the new MCAT. These infographics will help you understand which topics and concepts really matter, understand the new scoring scale, and figure out when you can take the new test. The new MCAT is going to be tougher and longer. Preparing for it doesn’t have to be though. If you want to learn how we can help you prepare for the MCAT fill out the form to the right or give us a call at 888-530-NEXT.
