OP: It truly is much too early for you to be thinking about the MCAT. To the others with ambitious schedules:
Set aside a couple of months (ideally 8-12 weeks) devoted to MCAT prep. That’s my best advice, based on teaching MCAT courses for a lot of people.
MCAT is all about strategy and practice, practice, practice. It is not simply a problem-solving or recall test, and you need to understand its unique challenges. For example, you need to know which formulas to memorize and how to use others when provided. You need to know how MCAT math typically works (simple math, round numbers, nothing complex, never memorize constants). You need a very good feeling for the level of detail on physiology questions, and a nice strong mol bio and genetics background (just a freshman course is enough, but you need it). You need to know your weak points and where you make mistakes; you need to get the timing down perfectly. Especially if you have a low GPA from the past, you need to make your absolute best effort. The unhappiest MCAT students are those who try to keep working, taking courses, volunteering, taking care of kids, AND studying for MCAT…a recipe for disaster. Similarly, it’s a disaster to rush to the MCAT when you are not ready for it, especially with the idea that you’ll just retake if you don’t do well the first time.
