Easiest level 300/400 math course 24 points, 14 comments
“I know there is a post about this, but that is five years old, and looking at UWflow, some courses have been restructured. Any advice on what courses may still fit into this?”

4xx math courses 4 points, 10 comments
“Are there any 4xx math courses that only require a 1st or second year course as a prerequisite? For example pmath340 only requires math135, but I was wondering if there are any other math classes …”
u/TheRealArjun: “AMATH 456, 475 (not sure if pmath majors usually take those Calc 4, ODE 1 prereqs), CS 467 / PHYS 467 / CO 481 (same course), CS 436, 487”
u/TheRealArjun: “… more rigorously with the last third being an introduction to topics from control theory (AMATH 455 goes more in depth) 442 is just 342 with PDEs, so just be familiar with wave equation, finite difference methods.. …”

u/luizloo: “… I am for sure going to take AMATH 451 and 455, and deciding to take one of AMATH 456, 442, 477, 453. Has anyone taken these 4 courses? Which one is easier than the rest? Could use any advice/suggestion! …”

Are there any CS and CE grads/4th years that could give some advice and dispel worries about the programs to an accepted individual? 0 points, 11 comments
“Hey everyone, my friend got into uw cs and ce this year, and I’m asking on behalf of him since he doesn’t use this platform. Ce was his first choice until cs surprised him. …”
u/TheAllAwesome: “Cs is easier and actually has less required math (although the math is “more rigorous”).”
u/TheAllAwesome: “I guess it’s a stretch, but here is a control systems class in AMATH https://uwflow.com/course/amath455”

AMATH 456 or AMATH 455 3 points, 2 comments
u/wasteslayer: “Im taking amath 456 in the fall with Kirsten Morris but I saw really bad reviews of her. I need to take 3 400-level amath courses so I was thinking, should I take amath 455 (control theory) instead of amath 456? What is amath 455 like?”
u/Kakateo: “… Just note that if you want to take AMATH 455 just to avoid Kirsten Morris, she also teaches that sometimes. My friend took it with her in 2018 Winter I think, and he said it was really easy. …”

u/OrthogonalTrajectory: “what about filter design, signal processing, rigid body etc.”

Courses to take for Investment/Quant Analysis 6 points, 13 comments
“I'm a CS major interested in getting into personal investment (stocks etc) and quantitative analysis/portfolio management (especially the statistics/cs side). …”
u/Jyan: “You may want to look at control classes in either AMATH or ECE. Portfolio management is much more difficult than just finding a good statistical model -- you still need modelling, but in addition you …”
u/Jyan: “Control theory is AMATH 455 -- state space models and LQR/LQG will be of interest to you. Alternatively or in addition, Bersekas has a good book called dynamic programming and optimal control that may be of interest.”

u/ph0tone: “… Someone who took AMATH 455 - is this course more theoretical/abstract than "practical"/engineering? I enjoyed studying AMATH 451, and I'd like another course of that kind, and I've heard that 455 is related to dynamical systems. …”
