Rubbish i had a job of flicking through 5000 Cv's with a team of 5 to recruits for huwawi tech which is some big comm company now the "one to be workin for" and they couldnt giv a damn about spellin they were after just experience. im not sayin that spellin is somethin we should forget but i recently watched a program where instead of parents gettin better marks in o lvls after takin a crash course their children were doin better in o lvls than they did without learnin for them so yet again i will answer ur question
GCSE's R HARDER THAN UR O LVLS WERE FACE THE FACTS AND STOP MOANIN U WHINGIN BITCHAS
