tips for gen sci first year

^ title. i’m going into gen sci this year w hopes to do hsp bio. my first semester im taking bio, chem, physics 1201, psych, and calc. and then second semester i am taking bio, chem, psych, methods of matrix algebra, and earth sci 1089. what should i expect from the workload this year and what are some tips for managing it? another thing is i don’t actually know where my time management skills are bc ik good strategies for it but i was also insanely depressed in my senior year and my management skills and grades suffered because of it. i have also never taken physics and the only physics knowledge i have is from calc & vectors (which my school makes harder for uni prep but i finished w a 70 bc again depression) and chem (if that even counts). i want to maybe do grad school or med school so i have to take 1201. i’m still feeling some of the burnout from grade 12 so i’m actually terrified for first year!
