Maybe I read your post incorrectly, but I believe you need the botany and zoology in addition to Introductory biology I and II.
At least that is how my school is. Intro biology I and II are required for medical school.
I would agree with audeo, take Physiology before the MCAT. It is a wonderful class. My school lists it as Animal Physiology, but it was all human stuff. I learned soooooo much in that class. It really helped me on the MCAT.
I also took genetics, immunology,
bacteriology and microbiology before the MCAT. Any class you take should help slightly. maybe one passage per class. Good luck 😎 😎
