Just as a piece of advice to the OP and anyone else in his situation, assuming your marking system is not completely fucked it should be possible to get almost full marks on a question without actually getting it right (has happened to me before). What really matters is how you show your understanding of the method and concepts of the question and how different concepts link together. Just getting forum people to do the questions for you will not actually get you anywhere, you need to understand what is going on within the question and what you need to do to finish it even if that question is no the same as anything you have ever seen before. If you can't do this then you will never be able to pass anything but the most basic of problems (which are probably quite similar to things that you have done in class).
