I just took mine a few months ago. I did pretty well (A-). I left the test wondering if I answered correctly. Several of the scenarios have outcomes that were very simular - i.e. 'approach with a firm voice but polite manner', or 'approach with a firm voice and firm manner', etc...I was very unsure when I finished If I did well. This was a test for LEO and not Fire, so I am sure yours will be somewhat different. This test had about 50 scenarios, so I am not sure if it was 'the B-PAD'as mentioned above, but it was a video based scenario test that applicants take here in FL.
Before I took it, I was told to just answer as you really would, not to answer the way you think they want you to. Don't answer like you think they would on COPS or any other TV show!
I just answered with common sense...and tried to 1. keep the interaction with the public polite, 2. keep control of the situation, and 3. do not read into the situation, only use what is presented in the sceanrio. You will have about ten seconds to choose the best answer (usually 4 possible choices) to each scenario. There will be wierd scenarios, racial scenarios, violent scenarios, and other kinds of situations that might catch you off guard. I hope this helps...feel free to IM me if you have other questions.
