You can't study or prepare for the test. It's simple though. Most of it is about memory. They'll give you scenarios where you need to listen to a 911 call and answer some questions. Then there's what priority certain situations are and who gets dispatched. It's about 2 hours worth of testing. Dress nicely as if you're going to an interview.

Good luck and don't quit your day job. I passed the test, did the sit along, passed the background check and have been waiting in limbo for the next round. Since November... They told me they're still unable to hire so I've been placed in a waiting line.
