Got 72%, passing is >= 60%.
Actually failed it the first time by 2 questions, it's one hard
test, and SQL doesn't hold my interest as much as programming languages. Barely squeaked through part 1 for that matter. To add insult to injury, the test cost just increased from $195 to $245.
Definitely use the official study guide and do lots of practice. Lots of little minutia come up in questions. I created a set of 20 exercises that covered the basics of the 11 chapters and kept practicing them until little peeking was needed. Did not review the part 1 material, and did not seem needed. Still good to stay up on if time permits. The list of study topics on Oracle's website was fair.
Previous certs are
Java programmer, Spring Professional, Hadoop Developer, and SCAE Software Test. Plan to do Java web components next, then HBase. PHP and MS's Javascript certs are looking pretty juicy too.
