Just took the boards after taking the BTB course.
Review of Beat the Boards:
The CDs: Lame. I didn't like them at all. Put me to sleep actually. Better if you read with the reading material but then again, you can just read the reading material without the CDs. The reading material is almost transcribed CDs or the CDs are basically the reading material literally read out loud. Totally lame.
Reading Material: Kinda lame. The content wasn't bad but it was waaayy to wordy. No way you needed several hundred pages to describe Interview, HPI, risk assessment, Vignette, presentation and psychotherapies. The 'clinical management' portion was too brief and stupid.
DVDs: So-So. Parts of it were good. Live patients, where people made mistakes etc were good. The model examples were not that good. No models of vignettes. Again too wordy, it has a tendency to make you want to include everything in your presentation which is fine in a mock exam but not on the boards. People often didn't finish.
Live patients. The strength of the course. You can see several people interview and get reamed. But again, it gets too wordy. It may actually mess you up. It messed me up. I didn't finish even one of my vignettes and my interviewers kept interupting me to move me to the next area of the live exam. The best part is the preparation simply by practicing something multiple times. There is no substitute for that.
Well, we shall see how the result comes out.
I think this test is good if you are far away from your residency and can't have them give you mocks, if you are an IMG and have trouble with interviews or if you have failed. Otherwise save your money. The main issue seems to be anxiety and that can be dissipated by doing mock exams somewhere...anywhere. Practice presenting to a wall. Record yourself and listen etc.
