We focus 100-percent on preparing you to conquer the actual MCAT, which is why we build all our courses around the materials produced by the writers of the exam, the AAMC. For this reason, for the diagnostic that you will take during this course we’d recommend using the AAMC’s Official Guide Questions (purchasable from the AAMC for just $10). If you’d rather not use these official practice problems, however, we will also provide you with a link to a free diagnostic exam that you can take advantage of instead.
