So I'd have to enter a post-bac program if I got a masters first? If not, what constitutes a post-bac class? Any class related to Bio or Chem or Physics. Is 5-6 years too old for a class to be used independently without post-bac supplementation?
HawaiiHereICome, a post-bac class is typically any class you take after you get your bachelor's degree. These can be classes you've taken before (i.e. you're repeating for a better grade) or they can be classes that you haven't taken before (i.e. you want to show that you've maintained your academic ability and competitiveness).
If you're getting a Master's degree in the sciences, your grades in graduate level courses will speak to your academic ability (hopefully you'll get ALL As). I would say you probably don't need to take undergraduate level courses,
if you've taken graduate level ones immediately prior to applying. However, keep in mind that grades from graduate level courses are often inflated. To solve this problem, you need to get a strong letter of rec. from one of your graduate professors attesting to your academic ability
in detail.
So you probably won't have to enter a formal post-bac program.
Now, getting 14's on the science sections of your MCAT will provide pretty good evidence of your knowledge level.
If you're going to wait 5-6 years after getting your master's, I would recommend that you take a few classes (~3) and ace them to demonstrate that you can still get As. If it has been 5-6 years since you've taken a science class and you get 14's on the Biological and Physical science sections, I don't think you need to prove anything.
Sometimes, they just want recent coursework. Meaning it can be undergrad or grad coursework.
By the way, awhile back I was wondering about the same questions you asked in your posts. What I shared with you above, are the answers I learned as I went through the application process. Not a single school I interviewed at asked me for more recent coursework. In fact, when I mentioned at one interview that I was taking a molecular bio course, the interviewer stopped me and said "you don't need to tell me anything extra, you're more than qualified."
