Well just like I did with the CCENT, I finish up my material by going back through all of the books tables, scenarios, open ended questions, and late night labs. This is the time were I take all of the theory I've learned and put it all together. I go through the whole book again basically while setting up multiple complex labs and answering dozens up dozens of questions that's included.
Today I spent most of the time with VLAN's and STP, I finished up the day with going through one of the complex scenriaos included with the Cisco Press book. This lab was a mix of VLSM and OSPF along with manually figuring out routers IP addresses and subnets by looking at a network diagram. About 5 hours later and I'm finally done for the day part, I end the day by configuring a simple lab before I hit the hay. Tonight is going to be the easiest night, I'm just setting up a router with the basic initial setup and configurations with Telnet and so on.
