Take AP Chem!! For me, I believe that chemistry is more “similar” to medicine than physics and it would give you a good base. ap chem would also be easier for you since you are already taking chem plus ap chem is totally different from honors chem, at least at my school. pre med classes are extremely chem based since there’s various types of chemistry you need to learn in college so ap chem would give you a nice start even though ap credits aren’t accepted for pre med students.
