@vaporeon_ I got an F in linear algebra at Cornell University and when I told my advisor afterwards that I was developing an interest in Physics she told me that "I don't think that is a good idea" because I struggled in linear algebra
How did you improve at it enough to do physics?
bragging
@vaporeon_ anyway a few months after i passed my qualifying exam for my physics phd program and colleague of mine got their phd and so we students went bar hopping in celebration
one of the faculty who graded my qualifying exam was with us. while he and i were severely inebriated he told me that my performance on the exam was, by far and away, the best of any student that year
(you're supposed to keep these things a secret lol)
