  • The course itself is fine as long as you don't take it with Harmeen. listen to the reviews that say she is an awful prof. She's rude, inconsiderate and extremely entitled. Easily the worst prof at uwaterloo. She will take 15% off your final grade even if you submitted a VIF and had an emergency surgery. She does what she wants regardless of what the course outline/manual says. I could list 100 reasons why she has made my experience at uwaterloo miserable.

  • The course structure and expectations were not always clearly communicated, particularly around lab policies. The lab manual wording can be interpreted in multiple ways, but in practice the policies were applied However Harmeen felt that day. This created confusion and made it difficult to understand what outcomes to expect in situations involving legitimate absences.
    Communication around accommodations felt inconsistent. Even with proper documentation, the application of penalties did not seem to align with how the policy is written. It would help if expectations were explicitly stated and consistently enforced. You will probably have a better experience taking it with quite literally…

  • love the course, hate the prof. Do yourself a favour and DONT take it with Harmeen!!!

  • This course was far more frustrating than it needed to be, not because of the content, but because of how it was run by Harmeen. Policies outlined in the lab manual were vague and, in practice, applied in ways that didn’t match their wording.
    Communication around accommodations felt rigid and dismissive, even when proper documentation was provided. Overall, the course lacked transparency and consistency. Students are expected to meet clear standards, but those standards should also be communicated and applied clearly and fairly. Harmeen needs to do better.

  • Harmeen is definitely Waterloo's worst instructor & she ruined what seemed to be an interesting course.

u/Cynical_Ticket: “So I know I'm not the only one, but I feel like that exam was way too difficult. I also wanted to mention that its pretty pathetic how she forgot to put units for a good handful of the values on the exam itself and the fact that half way through she realized she forgot to give …”

0.25 credit bird courses? 0 points, 4 comments

“Spring 2021 is my last semester and I want to take MUSIC 116 but it's only 0.25 credits. What other bird courses can I take that are also 0.25 credits?”

[deleted]: “CHEM 237L (straightforward but time consuming) + BIOL 240L (not bad, some people complain it's hard because Duxbury puts tricky questions on the exam). These are the only 0.25 credits I know about. Look into Kin courses too.”
