I'm currently doing English Standard (wish i picked adv), IPT, Physics, Maths Ext 1. My marks for English, Physics and IPT have been somewhat decent, while my marks in Ext have sucked. Any advice on what I can do, how/what I can study/use for study, etc, so I can get a good atar. I gotta get at least 80 for my desired course, but would love to get above 90. Any advice is welcome on resources, tips, textbooks, etc.
