I have my final coming up in a month as well. It's a practical exam on the first day, and a written exam on the last day. Like it was said before, everything you've learned up to that point is fair game.
I'm not sure if you're studying off the same book as I am (Emergency Care and Transportation of the Sick and Injured by AAOS) but if you are the book has a website that has lots of helpful tools and tests associated with every chapter. It's been a valuable study aid for me. If you're not using that specific book, perhaps your book has similar online features.
