I was wondering if anyone has an opinion on what the best way to prepare for the GACE exams for middle grades. In short, my situation is unique; I am active duty Air Force and I am scheduled to retire this May. I have a professional certificate in middle grades (GA); however when I transfered over from FL I still need to take the subject content exam and have a new certificate re-issued.(That is what PSC is telling me.) Since I do not have a specialty, I have been told that since I am a male that I should try Math or Science, since this is where a lot of principals will need teachers. That is fine, but I am back to my original delima, what is the best material to use as study materail. Any and all comments are greatly appreciated. Thanks.
