QoS materials
I started last night on INE Vol1 QoS section and boy oh boy did I get a kick in the arse! For my written I pretty much solely used the QoS exam cert guide but now I feel like I'm way behind the 8 ball with QoS after some of the sections in Vol1 
What materials did you guys studying (or have finished studying) for the CCIE use for QoS?

And the 3560 configuration guide of course. You should know everything in it. Then I did my own labs and also blogged about the Catalyst 3560 QoS. The Vol1 on QoS is huge. You can skip the 3550 stuff though.

as far as books the QoS exam guide is great. End to end QoS network design is good to.

I've added QoS-enabled applications and end to end QoS to my safari library. Ithink I'll read over them before I continue with the Vol1 QoS section.
