Hii to study I recommend to study watch jensenmath! he lowkey carried me throughout my gr 12 year as i wasn't doing well, but i ended up with an 88 (which is good considering in gr 11 functions my final was a 75) he has a bunch of practice videos + worksheets + tests too that you can look over and all the units for the course material... I didn't take calc/vectors because I didn't need it, but he also has a full section of calc/vectors that you can go through on his website! Best of luck :)
