Passed this morning. Not by as much as I'd have liked, but passing is passing.
Had 4-5 sims just like KiscoKid described. Was a little surprised with the amount of multicast that I got asked about. Really needed to know multicast and port security better than I did.
Can't really compare with the separated exams for BSCI and BCMSN, I attempted the BSCI a couple of times and was close to passing both times. Part of me thinks the composite was easier than trying to separate them out, but there is still a lot of information that you have to know for the combined exam.
Multicast, Dynamic Trunking Protocol, and Etherchannel were probably the 3 items I feel I got hit on harder than I would have expected.
I used the following books:
From CiscoPress
1.) CCNP Self-Study: Building Scalable Cisco Internetworks by Catherine Paquet and Diane Teare
2.) CCNP BSCI Exam Certification Guide by Clare Gough
3.) CCNP BCMSN Exam Certifiaction Guide by David Hucaby
Also was able to attend an online class from Thompson NetG for the BSCI. All the material was good (recommend reading the BSCI book by Paquet and Teare before the one from Gough) but I do not think they prepared me enough for the exams on their own. Really glad I sat down and setup some of my own labs for routing and switching. Run through as many show commands and debugs for everything as much as possible. The theory is the foundation, the debugs show it in action.
