- I was fortunate to be a math major as an undergrad and took a special
- honors course in real analysis that started right in with topological
- methods (we sophomores felt like we had just jumped off a cliff!) and
- went on from there. Never took the standard advanced calc class, but it
- must surely be as you describe and thus does not meet the needs of a
- future theory Ph.D. The problem is that there is little room in the
- curriculum for any electives, let alone another course in math, so
- unless the existing courses change one is left with dropping in on a
- grad course later on in your career.

- I would encourage any theory grad student to do the same. The trouble is,
- you would like someone to do this before advanced quantum, but usually one
- does not have the free time until after comps in the 2nd year -- which is
- a bit too late. Along the same lines, a good grounding in finite groups
- would not hurt either, although the courses in a math department leave
- something to be desired from a physicist's viewpoint.
