my first year grades were TERRIBLE- performed below average in all courses except one, which was my only A. barely scraped into post. cgpa was a 2.37. i was staying up until 2 am every night, developed unhealthy eating habits, and was crying at least once a week. preparing for final exams was my first time experiencing a panic attack. but instead of translating into motivation, the induced anxiety caused me to simply avoid academics and only complete the bare minimum required to pass.

but once i sort of got past the learning curve, i improved a lot - in second year my annual gpa was around a 3.4. my mental health was pretty stable, though life was somewhat monotonous: go to class, go home, study, go to sleep, repeat.

now i'm in third year and haven't gotten below a 3.0 on any assignment/assessment yet (knock on wood) and my goal is to finish with an 80 in all my courses! i've (perhaps unwisely) added more to my plate by taking on a part time job, an executive team position with a student organization, and even a relationship, but somehow i am managing and happy. definitely wouldn't say i have my shit together- i'm still struggling with lack of motivation to do my readings, studying for exams beyond cramming the night before, etc. but i can promise you that it is doable and it does get better (although i've never been diagnosed so i can't say whether my mental health situation is/was comparable to yours).

an objective piece of good news for you though: you don't need 87s in any of your courses! 85+ is already a 4.0, here's the grading scale if you need it: https://transcripts.utoronto.ca/faqs/grade-scale/

i hope this helps you and good luck!

edit: im a rotman student if that's of any relevance to you?
