Beginner

Greetings,

I had to learn Novell by rude force and have learned a lot studying
documentations from support site, manuals, etc. I'd like to take the exam
for CNA and I'd like some reference for self study. Here where I live there
are no courses for these exams. So, any recommendations about books,
downloadable ebooks, online simulations, etc are wellcome.

My goals are NW 6, NW 6.5 and GroupWise 7 Certifications.

Thankyou in advance!
