Yeah, just retake it next year. I took AB as a class and studied the BC material every night or so in the 2-3 weeks before the exam, and I'm very confident that I got a 5. I also did the 2003, 2000, 1998, 1997, and 2008 audit BC multiple choice in addition to maybe 25-30 free response questions. After doing all of that there was very little I hadn't actually seen, so the test was a breeze.
