let me say a few things. im new........i just finished by non cal gcse paper higher tier of the edexcel board. day after is the cal paper *me thinks i visited this forum a wee bit late*
my exam was quite easy...im hopin for 95+. but i think my coursework 1 didnt go too well... it was about number stairs and i reached the 7th level with no problem, but im not sure abt the eight level....i didnt understand the whole sigma thing in the end...not sure if i got the correct final equation...
