This same class did the same thing to me at Princeton except I was an engineering major at the time. I had done well on the Calc AP exams in high school which the engineering department said placed me in MAT 202. On the first day of class the professor started summarizing "what we already knew" from high school about linear algebra and I had seen basically none of it with the exception of basic matrix multiplication. The rest of the week was ego-destroying as I attempted to get help from the professor and was repeatedly told (almost berated) that I should already know the answers to my questions from my high school courses.

I eventually dropped the course, left engineering entirely, and majored in a biological science. But the jokes on them because I self-studied a shit ton of math after I graduated and eventually went back to grad school doing ML+Physics. It turns out that I'm actually pretty good at Linear Algebra after all.
