AP Biology or AP Physics C

I am planning to take both, but I do not know which class I should take first (Jr / Senior Year). I am still undecided if I want to undergo a career in medicine or engineering. I always leaned toward engineering as I am good with math, but I recently started to get more interested in a career in medicine. Would taking AP Physics C during senior year hurt my chances of college admission if I decide to major in engineering?

No. People in my school take AP Physics C after (Honors) Physics junior year, while other take AP Chem or Bio 11th grade after (Honors) Chem/ (Honors) Bio 10th and 9th grade, respectively.

No. AP Physics C is traditionally a senior course since it requires calculus. Over 80% of the AP Physics C exams are taken by seniors, and I’m sure they all land in very fine colleges.
