easiest class i've ever taken in my life. if you just do your work well, you'll be in good hands. some TA's even give you the problem set answers during discussion so i recommend taking a section at the start of the week than the end.
rubin is just a little clumsy and disorganized sometimes. he doesnt include participation points but his lectures couldve been done by literally anyone who can read/speak in english (everything needed to be said was already on his slides that he would post at the start of the week)
nonetheless, highly recommend rubin's lecture.

I honestly loved Professor Rubin. I know it was his first time teaching in a long time, and so it started out somewhat rough, but overall I couldn't recommend him enough. What sets him apart is the fact that he cares about his students. He did give us hard exams but he fairly adjusted the grading scheme to account for this. I thought it was very fair class overall and if you wanted to spend hours getting A, you could. His tests were open note open book and his grading distribution was:

≥ 97% A+
90–97% A
80–90% A–
70–80% B+
60–70% B
50–60% B–
40–50% C+

Overall great professor.
