I see. Sorry if the post was a bit different to what you expected, I think I grab the wrong end of the stick :rolleyes:. I wouldn't think it wouldn't take too long. Week maybe, but it depends what the classes are like. Like I said in my other post (kind of) I would mess with classes to understand them. Write silly programs to see how the methods worked. I find using methods in may own way is better than reading about them in a book or on the Internet, because your practicing with them.
