Disclaimer: I have not received my grades and have not taken the finals yet.

Totaro is extremely helpful, especially during his office hours.
Halfway through the course, I realize I was missing out on many of the points he was saying because I was busy copying the board (he writes like, real fast. Idk how his wrist is taking it).

So I recorded every lecture and added in what he said into the notes - helps a lot in tackling a tough class like this.
