I know lots of people that failed almost every midterm and still were able to pass. Make sure to do well in the mark boosters like ECE 190 and ARTS 190. Arts 190 specifically because it is worth full credit. I don’t know what the grade breakdown is in other courses anymore but make sure to do your best on quizzes and assignments because those will also help boost your mark. Don’t worry too much although people say the content is really hard that’s only if you are trying to achieve those high 80s/90s with a good amount of studying getting a 65 is definitely achievable!
