Looking for help developing a roadmap to a medical school-friendly degree

[muu9]

Hello, I'm trying to develop a roadmap to get a degree with a GPA over 3 (and preferably above 3.5).

Currently, I have:
(CLEP) College Comp, Calc 1, Intro Psych, Intro Scoiology, Chemistry
Ap Biology
Physics 1+Lab from a state college ©
I'll probably be taking upper-level classes like OChem from a community college in the fall since that's the cheapest option.
Do Saylor courses come with a grade? If not, which programs do?

I'm considering Charter Oak State College since they give generous credit for a 40th percentile GRE score, which seems like a very efficient way to get credit, but their "general studies" title might not look as good to adcoms as TESU's BA in <subject>.
If I did go with TESU, I would probably choose a BA in Math since https://westcottcourses.com/ exists. (Does something similar exist for other subjects?) 

The mcat might also be an issue- I am a pretty good tester (99th percentile SAT) but I don't know which of the mcat's prerequisites are absolutely necessary and which are just nice to have. Is it worth just studying CARS/social sections and waiting till I take biochem in a proper class, or should I just bite the bullet and self-study biochem now?

I'm not sure if this works, but I would like @MSK9 to weigh in.
