In high school:
Algebra- Failed. Twice
Chemistry: Failed
physics: failed

after I grew up a bit:
Math: made it through second year calculus and (barely) two terms of differential equations. Threw in a year of scientific computing to boot.
Chemistry: Passed a full year of it.
Physics: Did well enough to get a degree in it.

Also, took advanced topics like graduate level fluid mechanics and marine optics.
