I must have posted in wrong subforum:
I did IMO and math camp in high school. I also took AP tests and differential equations and linear algebra at college level as a HS senior. Then I took abstract algebra, real analysis and topology freshman year. Then I took algebraic topology and functional analysis and commutative algebra sophomore year. I took Putnam as well and REU. Junior year I took algebraic geometry, algebraic curves, abelian varieties, and model theory. Senior year I took spectra and stable homotopy theory and representations of Lie groups, algebraic K-theory, chromatic homotopy theory and a special seminar on higher category theory.
I was thinking of math grad school but realized economics is probably easier to get tenure in. I think I should be fine with my background.
