Martin,
The BIG envelope should contain a header sheet, a HPR application, a what I call Key Sheet, although it has a different name, and a letter envelope containing the exam. The so called "key sheet" has all the same questions that are on the NAR site, which is why I don't mind people using it. Moreover, it gives you not only the answers, but a "why" at the end of each question, which is much better for learning. Just don't open the letter envelope.
As far as where you got the exams, Steve is the guy I replaced in August so that is no problem. Still I will have to get the website updated.
Thanks for the info bro and good luck!
Carl
