i never went to lecture and exclusively read the textbook BUT i will note that i think he went over some content that either wasn't in textbook or i missed it while going thru the content, nbd though. bit of a weird quarter so not sure how much of my advice is applicable as midterm was online but i thought final was extremely fair (even easy). drops one hw -- i did find a few of the hws to be quite challenging but i did not go to oh or discussion which i know are always hugely helpful for math class hws so that is on me. overall i def recommend!
