Hello all, I am not sure if I am posting in the correct place. Im currently in community college, for now I think I am doing physics. Regarding the courses for physics, am currently taking mechanics and calculus 2. Spring I will take physics 2 which I believe is electricity and magnetism as well as calculus 3, and I am thinking of linear algebra or diff equations (possibly both). I have heard of REUs for undergrads, wanted to get some feedback of experiences, how the process works, when I should start applying (if I should), or any other information regarding.
