Same thing pretty much happened to me (almost the exact same numbers lol). I figured out my issue was timing, and I was spending way too much time on questions 1-15. I was trying to apply everything I learned in the CC, and spent a considerable amount of time second guessing myself. I would analyze your PT and see if you have a similar issue, as it's pretty common, and there are some good remedies for improving timing-especially on the easier questions. Either way, good luck!
