Taking this March 5th, i've been studying off an on for the past two months now. Having trouble finding time / energy. I have gone through about half of CBT Nuggets Videos(taking notes and labbing) as well as read through the entire Sybex book (did all practice tests, highlighted key points throughout book and wrote these out for future reference). Still dont feel prepared, I can answer questions but if asked to perform tasks in Windows Server i'd probably get lost, need more lab time to connect theory with real world.
I do want to point out that Microsoft has a great promotion going on right now for college students.
