After months of BSin around I finally got focused again over the past 3 weeks and started studying. I passed today with a 790 

I used Sybex 70-215 book, CBT Nuggets 215, and CramMaster practice exams which included a copy of Cram Exam book in PDF format. The test was 50 questions and I had 2 1/2 hrs to finish it. I finished it with about 50 minutes left. They asked alot of questions on Disk Management and Resource access on my test.
