When I started my as levels I was taking: Maths, Further Maths, Computing and the extended project. A few weeks ago I decided to take physics as well (doing it in my own time), I am committed to putting as much work into physics as I can, however without a teacher I sometimes feel lost and that I don't know what I need to know for the exam. Is it worth me going through this hassle or would my chances still be good if I were to get top grades in Maths, Further Maths, computing and my extended project? I am really passionate about computer science, my extended project is about the future of quantum cryptography if that helps.
I just think that maybe physics is taking my time away from other subjects especially since I am 8 weeks behind everyone else, and the fact that it generally seems to be a harder subject than the others I am doing. I do plan on applying to the top unis. Thanks for your input.
