to pass the exam ?

Are you tight on money? You can get Gibson's book for $10 on kindle.

Are you on limited time? Gibson's book is a quick read and you can blitz thru Messer's videos by watching them in accelerated playback speed on VLC player. (That's what I did; 1.5-2.25x speed)

Do you have any other certs or relevant experience? If you do then the cert might be easier and I could understand using Messer's videos only.
