Hello, I am new to this forum. Currently, I am a junior in high school, and I have been wondering whether I still have the opportunity to start a career in physics. For the past month or so, I have met a few other students who have an odd passion of the sciences, particularly physics. Odd, because almost everyone in our school hasn't an ounce of interest in anything involving academics. Until I met these well-informed students, I shared the same view as most others around me. Most of the science courses I have taken, have involved absurd amounts of worksheets and book work, with uninterested peers and uninterested teachers. This year seems to be a complete flip from that, where my science teacher seems to be much more passionate about his subject and can engage the class in discussion; and the fact that I have actually met other students who are interested. So for the past month, I have decided to learn as much about physics as I can. Mostly due to the fact that I was denied an advance placement physics course next year, because the teacher felt that I was not suitably prepared to take the class. Quite understandable, but it really pushed me to learn as much as I can, in the hopes that next year when class begins, I can convince the teacher to move me up to the advance placement course, rather than honours. Most of my classmates are already taking physics, and what I have noticed is that the entire course is only on classical mechanics. Most students seem to struggle, and while I have not learned as much as them; in just the month that I've been studying alone, I have learned almost half of what they have learned for the past 1.5 semesters. Learning without any guidance has been difficult, as I would spend hours in solitude trying to figure out the math behind what I've learned; but, I still seem to really enjoy doing so everyday. Unfortunately, next year will be my final year in high school and my academic record is abysmal. I'm not sure if it is plausible for anyone to be able to just take on something like physics this late into high school and actually be able to take it as a future profession; since from what I hear, becoming a physicist would require continuing to a PhD. I'm not sure if I ought to major in physics or leave physics as a hobby and pursue something else like computer science. For the record, the eventual goal that I plan on getting to is quantum mechanics. So would it be too late for me to reach that goal?
