NT Server 4.0 Certification Help Needed

I have written the NT Server Cert exam 2 times and have failed by 5% and 8%. I need some new study techniques to help me. I have been through ExamCram, Sybex, and MC Prep Tests, and old transcenders – and am fairly confident I know the material but I each time I took it my deficiencies were shown in separate areas. Each exam I took was adaptive and I’m sure the next one will be the same format. Specifically, I need suggestions on how to breakdown the scenario questions. (I already have Networking Essentials).
