I get rather annoyed at people moaning about being given a week to do an essay and that it has to be in tomorow. The hint is in the week bit, you could have done a bit everyday, or even done it at the beginning of the week, seen your teacher with the effort you have made, and tell them that other than what you've done you don't have clue. A week to do one essay when in an exam you'll probably have about 20minutes.
