Doctors! I want to become a doctor but high school chemistry isn't my thing?

You have two options:

1. Do well in chemistry in college. Get a tutor, form a study group, talk to your professor, study every day, do practice problems. Whatever needs to be done.

2. Don't become a doctor.

If you want to be a doctor that badly, you will find the motivation to push yourself to succeed. In college, you will have professors that are terrible. You need to learn how to succeed in those classes anyway.

You definitely need to learn chemistry because it is very important in becoming a doctor. I am going to apply to medical school most likely when I am done with my math degree and I have taken the prerequisites and some people who went in with high hopes, have gotten slaughtered by chemistry and they decided to give up. If you find chemistry hard now, it will only get harder unless you buckle down and find out what you're having trouble with and fixing it. You need to get a tutor or extra help from the teacher. You need to take notes and be serious in class. If you don't understand something, ask the teacher or classmate. Maybe even move away from friends. Sometimes that helps. You process information a lot easier because you have no distractions. Take notes during the lecture, asks questions when needed and do your homework and problems every night. If you do this you will for sure raise your mark. Tutoring helps a lot.

Normally high school chem teachers are terrible. At least back in high school everyone I had ever had or heard about was bad.

College chemistry is a lot better, you have people that actually like chemistry and understand it. You also don't do useless things like memorizing the periodic table (every high school chem class includes this for some reason).

Honestly? If you can't handle high school chemistry, you won't be able to do college chemistry. Especially not the dreaded Organic Chem. There are many other professions you can consider.
