Only bother trying if you're incredibly dumb and need to revise to get A's and A*s. Below that is just worrying or pure lazyness. Basically, GCSE's can never make you look good, but they can make you look bad, so don't fail them, get all A's +
Wow. To be honest I'd rather get all Cs than be a stuck up, undermining 'smarty pants' like you...
