I would like to, but unfortunately I'm fairly locked in, my rationale being: I have to start the Chem series to be ready for the MCAT on time, can't move that. If I pushed Physics back, I'd be taking it alongside Organic Chem, which would be even more difficult. Don't want to move Calculus because I'm coming right off of Precalculus so it'll be freshest in my head. That leaves Cell Bio as the last option to shift, but there aren't many other viable classes to use as a fluff- I've already completed virtually all general education classes, and the upper division biologies use Cell as a prerequisite. Hence why I'm here 😅
For Heaven's sake, do not take this courseload. This schedule should make you nervous, because this is an absolute recipe for disaster - especially since you have had a "long hiatus" from higher education. You need to listen to
@gyngyn and start
slow.
It sounds like you are a career changer taking your prerequisites for the first time. As such, you do not need "fluff" classes or upper division science courses unless you are intending to significantly repair an established low sGPA. My advice is to save yourself money, time, and heartache and drop cell bio. You probably don't need it.
If I were you, I would take calculus + one other science lab course and see how you do your first semester back. If you can achieve a 4.0, then add on another lab class for semester #2. Be prepared to spend up to 80 hours per week on your studies and ECs.
There is no "on time" for the MCAT. You will be ready to take the MCAT when, and only when, you are scoring above your target score on official AAMC full-length practice tests. You will be ready to start preparing for the MCAT (meaning least 3 months of full-time prep) and then take these full-length practice exams after you successfully complete the following coursework series: general biology, general chemistry, organic chemistry, physics, biochemistry + an additional semester of general/intro psychology.
If you are serious about doing the best you can in your postbac, you cannot fall into the trap of being overly committed to a specific timeline. That's how nontraditional premeds crash and burn. I've seen it happen frequently throughout my time here and in my real-life premed advising. Banish all thoughts of "timelines" and ease yourself back into college at a reasonable pace.
Source: I am a very nontraditional third-year medical student who completed my DIY postbac when I was in my early 30s. I did not even consider taking 3 heavy science classes in a semester until I was a year in to my DIY postbac, and I
never took 4 BCPM classes at once. I ended up with a 3.98 postbac GPA, 90th percentile MCAT, 7 MD interviews, 5 MD acceptances. I treated this process as a marathon, not a sprint, and I strongly encourage you do the same.
