Hello everyone. My name is Brad, and I'm currently trying to get into OCS. I have, as of yesterday, taken the preliminary exam twice. I followed my recruiting officer's advice by purchasing a few books for study guides. I don't know how many poeple in here are already in, or graduates of OCS. But for those of us who are just trying to get in, they have changed the exam in the past few months. The study guides that are available at book stores are now out of date. Just in case my second attempt is not competative, does anybody know where I can get current study material?
