Have you not noticed that your topics have been closed since you are asking for help with problems for which you have explicitly been instructed not to get outside "live" help?
Is this fair to those against whom you are competing?
I really feel sorry for Makaveli, he is clearly trying to undertake a course which is far behond his capability. Let's assume Mark does give you the answer to every question you post, which I assure you he won't. What happens in the next test, and the test after, and grad school, or when you become a "professional" in your field and you know hardly anything about the topic you're supposed to be a professional in?
I believe the OP is posting questions from a competition, and has been clearly instructed not to get outside live help, on forums or from tutors, etc.
