Noooooo!
Katt Babes, it is really tough when that happens, but please do not be disheartened. More importantly please do not take it out on yourself - it simply isn't worth it. Speak to your tutor about it - it may be possible to have your grade improved, but if not what he says will help for future projects, whether at college or in the workplace. You are doing really well on your course - I recall you saying you'd won some award for being such a great student, so one dodgy coursework really doesn't matter.

*big hugs*

And don't you DARE drop out - US towns need your expertise.
