While I think it's good to think about occupations in high school, you can't equate your high school grades to you collegiate success. You still have 2+ years of schooling to go through post college.
For example, in high school, I had a 3.96 GPA UW, 4.25 GPA W with a 24 ACT score. I worked hard in my classes.
When I went to college, I had to study so much more. I even failed a class, withdrew another, and got a C- in Calculus. It isn't a walk in the park, and it shouldn't be.
I have a 3.34 GPA and a 3.6 science GPA. I'm applying this cycle, and as long as a score about a 60 composite (which I should), I'll be a competitive applicant to most schools.
My best advice to you is to get pharm tech degree and work in a pharmacy. This would be the best thing for you!
