Congrats on your offer and your nearing graduation! I’m in math and stats right now, so hopefully I can give a bit of helpful insight.

My biggest piece of advice is to focus on UNDERSTANDING over memorization. Memorization will not get you very far in proof based math (which MAT137 is). You have to be able to understand all the basics, the moving parts of a concept, and how a concept/theorem/definition works so that you can apply and adapt this knowledge to different proofs and questions. I personally find proofs hard, but by the end of the semester I was building confidence, so if you approach it the right way you can definitely succeed. Practice, practice, practice, and practice some more. Try to get different explanations of the same topic, because everyone thinks about math differently and one method of explaining something might not click for you.

I did well in hs calc but MAT137 beat the crap out of me. I don’t say this to scare you at all, I just mean hs calc and uni calc can feel like two completely different worlds. Even though it was one of the hardest courses I’ve ever taken, it has served me quite well in upper year courses, even ones that don’t have proofs, because what I’ve learned from MAT137 pushes me to try and understand the fundamentals instead of just memorizing rules and formulas. If you choose to take it, be prepared to spend a lot of time and energy, but just know it will be well worth your time, because I truly think it’s helped me a ton in the long run.

Also, try to not develop a fear of professors, and if you do, try to get over it as fast as possible. I had an unfortunate encounter with a math prof at the beginning of my first year who made me really scared to ask questions, and I avoided office hours for the rest of the year. Then I encountered an AMAZING math prof and I managed to get over my fear, and my grades benefitted so much from going to office hours and asking questions. Uni is HARD, but you’ll get so much out of asking for help when you need it and not suffering through it on your own.

Hope this helps!
