Well, I will prolly not hear the end of it, but I did it at sheble back in sept., really wasn't that bad. Wasn't easy either. I would say go for it, they will get you done, but be prepared to take an extra day or two. pm me if you have any other questions.
If you don't cut yourself short of the knowledge, you will be fine. If you go down there without doing any prior studying, its going to be a lot harder.
