Graduating Senior -- In need of some guidance! Hello Physics Forums, I'd like to start off with the fact that I've read quite a bit on here, and I have seen and appreciated how helpful and generous everyone is with their opinions and information. I'm here now to ask for some advice. I plan on double majoring in Physics and Mathematics in University, and I want continue on into graduate school and so on. I am a senior in high school, and while my grades were sub par (3.4/1950 SATs), they do not reflect the time and effort I plan on putting into undergraduate college. Along with these grades, I did not take the opportunities to advance myself academically, and so I am only completing Calculus AB and Physics B this year. I know a lot of people have these courses, and sometimes more, completed by the time they leave high school, which leads me to believe that I am far behind the competition. My question is this: Will it be easy, difficult, or nigh impossible for me to catch up to the "elite" of my college class? Thank you for your response in advance!
