  • pretty boring material and not a bird course by any means, but is not extremely difficult. Had it with peter macdonald and the lectures were boring.

Easy upper year courses 3 points, 13 comments

“I'm looking for 300 and 400 math courses that aren't too heavy on math and somewhat on the easier side. Do y'all know what courses are good for that? Thank you!!!”

u/ParmaMan: “A few I plan on taking: STAT 321, CO 327, CS 338, CS 330, CS 436. Note they are non-specialist tho so they might not work for your plan.”

u/Tazmaniaa: “… But is the specialization it recommends one of Stat 321 or 322 and there's no amath course required. Business courses are basically the same except you don't have to take marketing or policy. …”

Statistics options for science students 1 point, 3 comments

“As the title says, I was wondering if there were any courses that went into statistics and would be open for a science student to take. I'm in 3rd year chem, and I've already taken STAT202. …”

u/Laeriana: “Having STAT 202 as your only pre-req is kind of the biggest restriction, as most of the other open-to-non-math-majors stats courses (like STAT 321, 322, 337, etc.) that I know of require at least STAT 220 and 221, of which 202 is an anti-req of 220 and you may not be let in to …”

u/Laeriana: “… You are then further restricted as you would only be able to take STAT 321 (which is only ever offered in Winter terms), as STAT 331 (offered in ALL terms) doesn't accept MATH 225 as a pre-req. …”
