Ok, i think i have missed a few out
The ones you mentioned, sorry typed it in a rush and forgot the obvious, there was trig, but i would class trig as triangles as thats the section i studdied trig in when i was preping.
Its as simple as you make it, i didnt think it was hard as it involved very little working out as the figures was easy to work with. But i guess this will change depending on what place you go to take it. Its al covered in GCSE Maths so i guess its classed as pretty easy...
