Sorry to have to tell you this again, but your posts seem to have come from credit-bearing work, and are therefore not allowed.  I hate to use the word "cheating," but if that is the case, you are cheating.

One more time:  If you show work and ask questions for clarification, I would consider answering and/or responding to them.  Otherwise, NO help with quizzes or exams.
