So as of late, I've really come to taking a serious interest in physics. I'm in eleventh grade. I don't expect to go to a prestigious college like Harvard etc, just to get a physics degree. Throughout High School, I haven't been the best student, I haven't tried as hard or applied myself as hard as I could of, as a result I had gotten B's/C's and the occasional D in 9th and 10th grade. To add to this, my ACT score isn't where I could of hoped it to be. I got a 21 on the ACT. A lot of this is because of my lack of effort in the earlier grades, but I also think the test in general could be better. To add to the predicament, I had signed up for physical science in 10th grade instead of physics. However I have self taught a good variety of physics (not so mathematical). I also am in 4-tri algebra 2 because I had a B and C in geometry. I tried to switch into Algebra 2 (non-4tri) but the classes were full. However, this shouldn't be too much of a problem because I plan on learning Algebra 2B over the summer, testing out of it, and taking trig senior year. On the positive note, I've had completely all A's this year and boosted my GPA to a 3.3. This is mostly because of my new interest in physics and the want to learn. Is there anything you could recommend to help me improve my situation? Is it to late?
