This course was incredibly challenging, thought provoking, and often satisfying. The homeworks are very time consuming (they took me about 10-15 hours a week) and extremely difficult but TAs, professor, and fellow students make them doable. There is no better feeling than finally figuring out a proof. The final (worth 70%) was very challenging (I am pretty sure I got below a 60% raw score) but it was curved alot and everyone I spoke was more or less happy with their grade. This course is really intended for anyone interested in a Math major/minor.
Lectures are pretty typical for math courses; introducing concepts, definitions, theorems, and doing examples/proofs. The homeworks skew heavily towards proofs. The exam is split between questions that would be reasonable/easy on a Math 100 exam and proofs
The content of the course focused HEAVILY on proof. I went in with very little proof knowledge and did well but it is definitely something to consider going in. Go to office hours as much as possible, in my experience the TAs/Professor are more than willing to support you. Also make friends/study buddies; collaboration is genuinely encouraged which is something you should take advantage of.

Phenomenal class with a great professor. Convinced me to take a combined major with math. I found IB Math HL easy, but this class works with proofs and you will learn a lot. Getting an A isn't too hard so long as you finish the assignments, but you WILL work for it. Scaled Generously.

Hard yet great class, I've already taken IB Math HL and thought I would learn only a little. How wrong I was. Incredible professor.
Do homework early and then redo it later on in the course.

This was a super fun course, but also very challenging. It's the kind of challenge that will push you to learn and expand how you think. It starts out very challenging, but gets better as you go.
If you enjoy math and are strong in math you will do fine and should stick with it. Be prepared to spend a good amount of time thinking through the homework though.

Honestly, the most fun yet challenging class I took in my first term at UBC. Prof. Martin was very accommodating regarding covid and ensured that we prioritized our mental health. The class itself was challenging (especially the homeworks), but the exams are generously curved so it isn't impossible to do well overall. 9/10
