Hi
@Detective SnowBucket -
It's important to keep in mind that the MCAT has a specific "flavor" of how it tests biochem. As
@workaholic181 mentioned, there's crossover with chemistry and physics, they love to ask about certain applications such as predicting AA residues in certain parts of a molecule, and so on. Plus there's a certain art to reading the dense biochem passages on the MCAT in a timely & efficient way. This is why I always recommend that students build some realistic practice into their study plan even early on in the process, when you still might have some gaps remaining in your content -- the earlier you start training your mental muscles for MCAT-like thinking, the more effectively you'll study the content and the more chance you'll have to build the mental habits that translate into success on the MCAT.
With that in mind, I would definitely
not recommend only starting MCAT biochem 1-2 weeks before Test Day, even if you're taking a great biochem course at the same time. I would very strongly recommend incorporating active and realistic practice early on, even if that means that you miss some questions on content that you have yet to study in depth (for such questions, the idea is to focus on how you would
use a piece of knowledge). One strategy that you might use would be to study MCAT biochem at the same time as you cover the topics in your biochem course -- so after you do lipids in your course, you can go back and review the lipid-related topics that are tested on the MCAT, alongside whichever practice tests/exams you're doing. That would help you get the most benefit from the biochem course you're taking.
I'd also second
@workaholic181's advice to consider postponing. Although I don't know the details of your situation, I'm always cautious about the idea of taking the MCAT immediately after finals, because it leaves so little room for error in terms of sleep cycles, restedness, and stress. Being well-rested and in a positive mind-frame can really make a huge difference on Test Day, and I've known people to get burned by scheduling the MCAT right after finals only to go in to the MCAT sleep-deprived and burnt-out, causing them to underperform compared to their practice tests. Even a week or two of buffer can really help in this regard. Anyway, you know your own situation best, but hopefully this might be some food for thought.
Best of luck as you study!!
