Band or AP Chemistry?

I haven’t decided fully yet on my major, but I am hoping to become a dentist one day. I did read on several websites that one of the sciences I would need to take is organic chemistry, which is why I thought maybe AP Chem would help me understand it more. However, when I took Chemistry I sophomore year, I did found myself struggling with the concepts, which is why I thought perhaps Chem 2 Honors would be a little easier for me to understand.
I know GPA won’t matter much for college, but I also want to be a valedictorian for my class, which is why I’m scared that I won’t be able to handle all the AP’s, ACT Practice, and scholarship essays.
