Just passed the written and feel like i need to say something. Really want to say thanks for all the helps I gained from this study group.
Test is 3 hours, 150 questions, single or multiple choices. If mulitple, will give indication how many answers. Can go backward and forward to check the questions. Passing score 58.
Highly recommend 1. Boson #1 and #3. You should make sure you either remember or understand every answer. Don't even give up hard ones. Only give up something you really think it is going to be nonesense if you have to waste your brain resource memorizing the answers. 2. Need to understand these topics in depth: VoIP, MPLS(mpls-vpn, mpls-te), QoS. Those are my failing points where i only read superficially, but not in depth. 3. Try to read the online CCO website as much as you can, here is my another failing point. 4. The rest are the usual stuffs that every one talks a lot: books to read: Doyle's routing, lan switching, cisco press QoS, cisco press mpls, Caslow.
Now it is time to crack the most difficult part: Lab.
