Problems with Lab #6!!

      I began doing Lab #6. I cannot believe how hard it is. I was able to do the first two without any problem but now I am stuck on the others. I just wish the professor would teach us first what he assigns us to do on the labs. I understand what he means for us to do (read ahead and learn) but for me, a newbie, it is really hard to understand what needs to be done if there is no one to explain it to me even if I read ahead. Especially now that things are getting a lot more complicated. I cannot get a bad grade on this assignment when I am almost finishing the course.
