I have found A LOT of resources out there for studying for CCIE R&S LAB exam. Currently, I"m working on studying for my written.
How difficult is the written exam? I know the Lab is a doosey (sp?)... but I haven't seen much on the written. I've read through the Cisco Press CCIE R&S study-guide, am going through it again, and will then read "Routing TCP/IP" books. How much more should I expect to read before attempting this exam?
