I don't know. I found it extremely simple, to use classes. Took me like 1-2 weeks to get the hang of it. Ofcourse you need to practice to do more complex things.

I watched video tutorial from jonathan sampson, try search for him on google! Extremely good tutorials where he talks and explains classes(again; only the basics, but once you understand that, you can understand the more advanced OOP tutorials that are written, and not filmed).
