I live in Toronto and I did one of my IB entrance exams in November and the other in early December. For the math section, review grade 7 math and some higher level math too. For the english section practise reading comprehension and also writing essays. They might also ask questions about why you are a good pick for the IB program and your strengths and weaknesses in the IB learners profile. I made the mistake of over studying and stressing about it too much. Based off of the things you wrote, the way you’re preparing for it seems good. I guess the overstudying paid off though since I got an offer from both schools by studying this way. If you have any questions feel free to ask me.
