I just finished my sophomore year in high school( in 2 days I will have), but I only fell in love with physics this year. I never gave credence to mathematics till' now and I'll only be doing algebra II next year. My grades range from A to C-, and I've gotten so used to not studying and still passing, that I don't entirely know how to study (but I think I might know what I need to do). First question: How do I get the necessary courses for high school taken care of at this point? i.e. Mathematics and basic physics Second question: How do I get the experience needed to get into graduate school? Third question: How do I afford the money to get a PhD? p.s. I'm aiming for a PhD in Particle Physics. more specific then that, I'm not sure yet.
