I just passed 70-215 with an 820, not as good as I would have liked, but it's a pass. there we justa few things that I hadn't heard of before. Some of the questions were almost word for word from Transcender. I used that, exam cram, a sybex book and something from MS that I picked up at Boder's outlet. I would say Transcender had the most accurate questions, but each covered some things the others did not, so it's a good idea to get multiple takes on the subject. 70-218 awaits :P
