Fun math!
I'd already taken care of my math proficiencies at this point, so I just got to learn what I needed to round out my knowledge to prepare for calculus and study other useful stuff that I had been having difficulty learning about. In the first semester, I focused mainly on more advanced trigonometry (law of sines, cosines, etc.), and in the second, I studied linear algebra (though most of my time went to stats).
TrigonometryI spent most of the first semester studying trigonometry through Khan Academy. I just started by progressing through Khan Academy's precalc unit, and I ended up getting really invested in trigonometry. I really like visual geometric proofs backed up with nice algebraic proofs, so trigonometry was kind of perfect. And I learned some pretty useful stuff! Note that not everything below is trig: there's other math in there too.

Linear AlgebraAfter spending an irritating amount of time on limits (which is a useful concept to understand, it's just pretty boring once you get it), I decided to turn my attention to the math of vectors and matrices. More than once, my lack of understanding as to how they really work has held me back in computer science. So I deviated from Khan Academy and turned to the wonderful "Essence of Linear Algebra" series by 3blue1brown. I highly recommend that channel to anyone who cares about math (and more than a few that don't). He doesn't have as much raw curriculum content as Khan Academy, but what he does have is top notch. Notes below, again, not all linear algebra.
