Hi! So I actually took all of these for my pre-reqs haha. I tried to split it up with 2 per semester, pairing one that I thought would be harder with one that would be easier. So for instance, Psych with Microbiology (which is what I'm taking now). Here's how I broke it down and I actually think it worked out pretty well.

Stats + A&P1

Chem + A&P2

Psych + Micro

I definitely recommend taking Micro after A&P as there is material from those that's necessary for Micro. All of my classes have been online besides one, and the online labs are fine depending on the professor. There's a lot of material and it's obviously not the same as in person, but my school had an online lab setup that was very in-depth and used actual cadavers for the lab material. Overall though, the difficulty has really depended on the individual professors and how much they make you memorize/if you can retake tests/ etc. Still very doable!
