SDN Members don't see this ad. (About Ads) I'm taking the MCAT in August and I've been taking pratice sectionals(Kaplan). I'm consistently making 80-85% on Bio and 65-70% on physical. But there's no grading key so I have no idea what scaled scores these %s whould correlate to. I understand it varies with the body of test takers, but there must be some general guidelines for %s and the scaled scores. Anybody know?
