What topics should I cover the most?Watch
I have 1 - 4 grade covered but grade 5 - 9 stuff is 50/50 at the moment, I was thinking of focusing straight on grade 5 - 7 topics since those are going to be the big bulk of the questions in the exam.
I'm using mathsgenie for reference, what topics in the grade 5 - 7 should I cover?
Do algebra and graphs. They'll be the root of a lot of things in the 7-9 bunch. Learn about completing square, turning points, functions should then come naturally. Types of graphs and perpendicular. It improves the way you think on a general scale.
