Taking this course with David McKinnon. The whole course is excellent! He always tells some jokes in class. But maybe sometimes, the assignments are out of the content. David said, "It is a 4th year Pure math course now, you should deal it yourself." But he published his note online, so you can learn it in advance.

UW Math "Must-Take" Upper Year Math Courses 16 points, 10 comments
“What would you say is a useful upper year math course that everybody should take, regardless of their specialization?”
u/MeowntainDuwu: “What major? I can only answer for PMATH. Beyond the required courses: PMATH 453, PMATH 467, PMATH 446, PMATH 441”

u/BlazingMuddy-6305: “… For the PMATH 400s requirement, I plan to have PMATH 440 and 441, but for the last slot I'm still indecisive between those in the title. The problem is that according to my study plan, I could only take PMATH 446 next term. Could you guys give some opinion 🙏? …”

“Is anyone else enrolled in any courses you find exciting next semester? I'm super excited about a few of mine next term.”
u/dotuanhiep: “Yes, I'm going to prepare my anus for pmath + stats next term...”
u/BlazingMuddy-6305: “Wait what? I'm taking PMATH 348, 365, and CS 371 next term. I think I'll skip 450 next term, though. My full list is undecided, but the fixed ones are PMATH 348 365 and CS 365 371. My last two slots are for CS 486, PMATH 441 (yes...), CO 444.”

u/BlazingMuddy-6305: “Hmm... should I start emailing the professor Wentang Kuo to enroll in PMATH 441 (I will be taking PMATH 348 next term)? Also, I'm wondering, how was the course or the professor? Other than that, it seems that I have PMATH 365 with Stephen New and CS 486 with Alice Gao :O”

Love the marking scheme of PMATH 441 39 points, 5 comments
u/Hyacinth_s: “Either you pass as a 100 or fail as a 0, sounds good to me lol. Basically you take product of best 10 out of 12 assignments, where individual assignment mark is determined by rounding to nearest integer (0 or 1).”
