What have you covered so far in class? When does the teacher expect you to turn this assignment in? Is the assignment posted online, will you explain only the parts of the assignment that make sense to you, or should we try to guess at everything and just "wing it" for a solution?
The top left and the top right parts of your diagram looks fine to me. The center section is very confusing. I can't see any of the bottom third.
Please see my post above. Show us your assignment (all of it), and what you've done so far (all of that too). Once we understand what you've been asked to do and what you've done so far we'll have a better chance to help you... Right now we are just guessing, and anything we might say won't make any sense to you, to us, or to anyone else.
