Pretty much everything lol. I've got in 2 days anyways so at this point I'm just hoping for a pass.
at this point just do practice questions in things ur most confident at in order to secure marks. know ur formulas atleast they’ll get u somewhere. and after ur trials, try to to atleast 3-4 papers a week (trust me it’s actually not that hard it’s take abt 1.5hours for me to do) and you’ll learn the content like that especially if u look back at ur textbook for questions u dont get. that’s how i learned my content. i didnt look back at my textbook upon studying for trials a few days ago bc ive already been doing past papers with the help of text book formulas/examples to help me get the question. ive seen some ppl attempting textbook questions the day before their trial exam and i dont think thats the right way to go abt it (unless ofc u dont get a concept at all, then go thru it)
but honestly ur on ur way to score a band 5 and higher in math if u stay consistent and try many past papers, and make sure to review ur mistakes!!
