Guys... don't stress!!
Although it is extension 2 and yes, it is a demanding subject.. the markers are considering you a great student before they even read your work.
They are looking at it from the point.. You gave it a shot. Yes sometimes its really sad to see a year's worth of work just gone to a waste by handing in some scrappy thing thats about 2000 words over or under your limit.
Be positive and proud of yourself, that you gave it a shot. Sure we'd all love to get higher marks then everyone else, but no matter how hard you try friend, someone will always be better then you -- just be happy that you're doing Extension 2..
I know for my school we started off with 25 people doing ext. 2 .. now we only have 6 people... less then half dropped out.... AND YOU AREN'T ONE OF THEM!!
Goodluck ya'll
