Hello, I was just wondering what kind of options were available to an undergrad mathematics major during the summer. I know reu's are out there, but I was wondering if there was anything else. I would much rather take math courses over the summer as opposed to doing research, but the university that I attend is only going to offer a number theory class. So I was wondering if anyone had any ideas. Also, my math background by the time summer rolls around is: calc I-III, ODE's, probability theory, statistics, and an intro to proofs class. Thanks in advance.
