Best advice i could give DO PAST PAPERS its the best way to get better a maths. Any topics you dont get use sites like mathswatch.
I agree with this.As this is what I did and I went from a C in year 10 to an A* in year 11. Mathswatch is a godsend from heaven and I owe my A* to it

Well look at what part b is asking for. You first need to find the area of the triangle before applying a certain percentage.

What do you mean like terms? Do I add all the surds up from each bracket?
