I have a child who graduated from U of T (non-STEM) and a child at Waterloo (STEM). I also graduated from U of T in STEM.
IME, STEM students have a higher stress level than non-STEM. With STEM students, the stress eventually works itself out by upper years. The stress comes from being at the top of your class in high school and finding out in university that you’re no longer at the top of your class. AND from worrying that you won’t get into grad school.
Reddit attracts a lot of complainers, imo. It’s also been exam season recently.
My non-STEM kid had a direct correlation between effort and grade in his classes. He got plenty of As.
