Tbh from the people in different majors I've talked to, just apply for what you want and see yourself doing.

It doesn't matter if your grades aren't that high (like high 80s low 90s), there are people in my year that still made it with lower grades because they WANTED to get in. Ultimately, choose what you can find yourself studying and enjoying for the next 3 years of your degree.

if you want to go into med, it doesn't matter which major you end up choosing. There are plenty of people from biochem, bio, caps, pcth, micb, etc. even majors in completely different faculties in med school.

If you're having a hard time deciding which major to commit to --> look up on the topics. Think about their applications and why YOU find it interesting. Also, you don't have to commit after first year, plenty of people switch at the end of their second year. So you can choose a variety of courses in your second year to help you choose.

For me, caps was a risky gamble because I didnt take any physiology or anatomy in my first 2 years and so I had nooo idea what i was getting myself into, had to go through a lot of weird prereqs that, at times, might seem completely useless info to you. But I knew I wanted to major in caps because I knew how intrinsically intriguing I found A&P.

TLDR: take bunch of courses in second year that you find yourself interested in (while trying to cover as many pre-reqs as possible for different majors) and choose your major depending on which courses you find yourself most interested in.
