It’s not a hard test, you have to however apply yourself and get in the "hours" of studying..

Materials :- Transcenders (Good material, use them one week before the exam)

:- MS Press Networking Essentials 2nd Edition

:- This site.

The above is all you need.

LEARN THESE!!!

 Somebody sent these to me two days before the exam
I knew all the answers,  you should too

Good Luck
Mark…
