Question 24314
You may ask a specific question that you are having problems with.  Some of the tutors have lessons online as well.  If you search around the sight, on the home page or on "for students" you may find a lesson you need.  You can look at the problems others have asked and the answers given and sometimes that will answer your questions.  It is like a homework site.  We help with what you are having trouble with.  So if you have a specific question, ask it.  Or just look around to find the lessons and examples that the tutors have made.
Hope you find what you need, it is a little confusing at first, but keep digging, it is a great site once you figure it out.
