well im gonna say that there's gonna be trignometry including either the sine rule or the cosine rule. as it did not appear in paper 2. they always ask trignometry. another is maybe transformation. they asked a lot of transformation with matrices in paper 2. i also suspect quadratic equation, direct variation, sets, and plotting graphs.. another question they always ask is vectors. where they ask 'express the following in terms of ' this is a question they always ask. the quadratic is easy for me and we always get 4 marks off of it.

also another question about paper 2. does anyone know the answer to the question where it gave us the scale value and actual value of a car's windshield (i think), and trunk. we had to find the 3 missing values. it was worth 3 marks and i think i lost those 3 marks.

well paper 4 is tomorrow and cant wait for it to get over so i can get maths over with.
