Cossa was my favourtie first year professor. People are scared of her because she is to the point and makes you work hard. Read the textbook, go to class and work hard on your report and there is no reason you should get a bad mark. If you read the textbook and go to class, you shouldn't have a problem getting a good mark on her midterms.

I would like to say Rita is a nice professor although the course is not easy generally. You should be aware of the situation that your group project mark for presentation is probably to be very low but you still have opportunities to get A+ or A in this course with the help of midterm, final and every participation marks. Also, Rita is very CARING.

It was really disappointing, & I've never seen grades so low. I didn't know anyone who enjoyed the course. It was a big course load with weekly quizzes & readings. If you have a course with her, make sure to spend an obscene amount of time on citations - it could tank your assignments singlehandedly. Even missed periods on citations lose marks.

Participation mark is hard to gain. She talks too much on unnecessary stuff and leave not much opportunity for people to participate. The things she yaps about is not relevant to capsim or the assignment. Please avoid at all cost.

You can't even avoid her, so not much to say there but she is genuinely the worst professor I have had in my three years at McMaster. She's not even a decent human to interact with as she seems pretty egotistical about her salary. She's so strict in rounded and even if you are 0.02 away you won't get the round up unless u attended every lecture. GL

shes rough. she claims shes generous cause she gives an easy 1% here or there but how does that make a difference when her exams are close to impossible?!?! just cause she wrote the textbook she assumes that we can all know it as well as she knows it. she is way too difficult for no reason, so excessive, avoid at all costs!!

avoid. avoid. avoid. she makes you PURCHASE many different things, uses evey platform possible. this girl is doing wayyyy too much like calm down. she brags too much about her personal life when literally no one asked or cares. she has a nice attitude but its extremely fake and everyone knows it. worst prof by far.

Rita is just a terrible prof. She doesn't care about her students and pretends to be oblivious as to why many of us don't like her classes. Her expectations are too high and sympathy isn't exactly her strong suit. Avoid her if you can.

She isn't sympathetic to her students and sets the bar way too high. She boasts about herself too much and makes her students feel miserable. If you ever think about rebutting or debating with her about grades, it's either her way or the highway. I would avoid her if you're taking 1E03 if possible, she's awful.
