For the 2nd question, did u find the angle in the big triangle and then take it away from 90 and then work on from there in the wee triangle? See the 3rd question, was the answer 175/176 or something like that?
Make sure you know ur sectors, probability and surface areas and volumes; thats where the big marks are in t6
I had a few lessons with a maths tutor because my teacher wouldn't teach us anything after the T4 exam in January, it was awful! My tutor definitely helped, I just need to revise the formulas and stuff
