i finished CCNA 4 tonight, so now its time to start the fun: studying for CCNA. going to review everything i feel i need to work on, and then i'm going to schedule for the end of January. I'm currently going to focus on getting subnetting down real well. I'd like to have the CCNA by mid to end of February, so i can start my CCNP studies off right... i start semester 5 in like February or march.
any tips? i'll be taking the 801, so without violating any rules/policys/laws, what areas should i particularly hit hard?
if anyone has any suggestions for labs that'd be great. i've got 7 routers and 3 useable switches on my rack right now (one of them is being used for my local network

also, if anyone knows, i have 3 2924 switches. is it possible to upgrade the memory on them? they have 1MB of memory and i need more to get a 12.0 IOS on it
