For those of you who have recently taken and passed or failed the oral board exam, would you recommend attending an oral board review course or doing a self study program? I understand that this exam is different than any other exam I may have taken in the past, so it makes sense that I may have to study differently. However, the time and cost to attend a review course is very significant. So if you attended a review course, which one did you attend and was it worth your time and money? And if you did NOT attend a review course, what book did you use as your primary source for preparation? Also, any other tidbits of advice are welcome (such as hotel to stay at, dress attire, etc.). Thanks.
