your a sophomore in high school asking us to give you our recommendation for what high-school level class you should take in 2 years? Do you see how silly that sounds
Fine I'll play along, your status says "pre-optometry", but I think the pre-reqs are the same as ours.... either AP bio or AP A/P is good IMO. I would do the AP bio because when you first start college, you'll most likely take Biology before any anatomy/physiology.
My advice to you is (and I know u aren't asking about this) if you are rally serious about a career in healthcare, do some shadowing now, its better than doing it when ur in college.
