I just passed the 4th of the four new MySQL 5 tests (DBA exam #2). Here's my scores for the various tests - Developer 1 & 2: 62, 59. DBA 1 & 2: 56, 58. (I believe each test has a maximum score of 70.) I have been taking these tests on & off throughout this year. My study resources were the official study guide in addition to a lot of hands-on experimenting.
