I'm a college freshman, who is thinking about majoring in physics. The problem is, that I suffer a lot of anxiety about whether or not I'm actually capable of going through with it. I didn't do all that great in high school, and that's why I'm at a community college now, but that had a lot to do with some personal problems that I was dealing with. However, I managed to start doing really well in my Junior and Senior year, when i decided that I wanted to pursue my childhood dream of being a "scientist". I took an honors level (I didn't even take pre-calculus yet, so i wasn't allowed to take AP level physics, even though it wasn't that different from honors level), and I did extremely well in it. My final score was 98%+ The thing that makes me nervous is that the only three people I know who are going into fields that are similar to physics are way above my league. All three of them had 800 math SAT scores (mine was about 650), 2 of them finished calculus 3 while still in high school, and the third got as far as Differential Equations in High School. I'm a college freshman taking calculus, and I'm doing well, but nowhere near the level that my friends did. My friend made an offhanded remark about how he's never gotten less than a 98% in a class, while I can never quite get scores higher than a 95, no matter how hard I try. Basically what I'm asking is, how smart do you actually have to be to major in physics? Are all of you on the same crazy level that my friends are? I'm the sort of person who panics a lot, and I'm terrified that I'll get past the first few years of lower level math and physics, and that I'll suddenly be overwhelmed by how hard it is, and that i'll have to change my major and lose a lot of credits, or that I won't be able to get into grad school and I won't be able to get a job with just a bachelors degree and a mediocre GPA.
