I've passed the BSCI and from what I remember, get to know your protocols, BGP, OSPF, IGRP, EIGRP, dead timers, update increments, administrative distances, metrics and of course the ole OSI reference model. I also got 3 interactive sims, 2 or 3 drag and drop command questions and 2 command line selections (list commands and you pick the one that best solves the question). Been a few months since i've taken it, preparing for the BCRAN on the 14th of Aug and now my mind is flooded with Remote Access stuff. Did a administrative core dump once I found out I passed. I'll tell ya one thing, transcender helped alittle but on hands experience really helped alot.
