The farthest to math i've gotten in high school was geometry and ended up with a D. In my senior year I ended up graduating physics with a D.. But I love astrophysics and want to pursue it since it's my passion.. Would colleges still accept me or am I completely a no brainer for acceptance now?
college physics, and certainly astrophysics, requires that you take and pass at least one year of calculus. you'd have to do remedial math just to get into calculus -- while that's possible, you'd have to be plenty determined
You may have to enroll as undeclared and demonstrate how you have improved in math and physics by taking the colleges entry level classes. Then apply to the department
You can get into a university, but that doesn’t mean you can get into a physic major. I would guest you wouldn’t be able to handle the work for a physic major. HS physic is but a drop of what you will need as a base for physic in college. You need a very analytical mind.
How were you at algebra? Freshman year of college take calculus. If you can’t handle it, look for another major.
