Should I reschedule?

I’m scheduled to take the MCAT September 4th. However, I’ve only finished around 70% of the content review (biology, biochem minus the metabolic pathways, gen chem). I haven’t even stated ochem, physics, P/S, or the rigorous parts of biochem. I also feel like I haven’t been able to do as much Anki as I had hoped because I’ve been so busy this summer, so my material retention is pretty poor.

While I do have a full time schedule this fall, the next MCAT dates are in January, so I have ample time to study + a lot more flexibility w/ time. January is pretty far out, and I’m worried I will lose momentum for studying.

What would you all do in my situation? There is a financial disadvantage too, but I don’t want to burn myself out by cramming until September just to get a score I am not happy with
