While these tests are not supposed to be predictive they usually are accurate withing +/- 5 pts. for most test takers. You're right on the edge with that score and depending on how you take tests and how much you study the next 10 days you might not pass.
I would suggest postponing your exam for another week and sitting down with FA for that whole time. Memorizing a few more facts out of FA certainly won't get you a 230 in that amount of time, but it should be more than enough to get you up 5 or 10 points into pass range.
Best of luck
