I took the 70-680 exam for the second time this morning and passed

and wanted to offer some input that may help others about to take this test.
The training kit for 70-680 is good for a foundation, but most people will need to use other sources as well. I would say 15% of my test included material that was not covered in the book or was just barely mentioned in the book.
My main issue with the test personally was that the questions on this test felt very incomplete. I took the test twice and on both versions the test left off some information that would have made the question clearer e.g. which edition of windows 7 was being run.
I also wanted to know if anyone else has had issues with the test crashing. The test crashed 6 times on three different computers while i was taking it and the proctor told me it was very common with microsoft certification tests. It was the first i had experienced, but wanted to get others input.
I appreciate the help this forum has given me and hope that the little bit i could mention about the tests will help someone else.
