Hey guys, I've been doing Metal & Engineering and i was wondering If anyone who has done the subject could share their notes/tips? I've been trying to ask my teacher for notes but he's just lazy. I've been also doing the BOS multiple choice questions but i feel like they are wasting time (are they worth doing them(?) and been doing past HSC papers. Even though I'm coming first (out of all the trolls, except a few people), I got 40.5/80 for my Preliminary and I really want to get a good ATAR (85-90). Please help! :'(
