Took the better part of a month to prepare, but scored a 894 ... I will admit it was one of the hardest exams I ever took. Much more difficult then the first exam in my OCP DBA certification.
I used the MS .NET Framework - Application Development Foundation Self Paced Training Kit Second Edition for the initital preparation.
Also used the MeasureUp practice questions, which imo is when the learning really started as each time I got a question wrong I would goto the MSDN to review all the material.
I also found various sites that offered information or practice tests.
