I cheated on a test and got caught?

Well, I was about to say that detention was more likely than suspension until I read your additional details. A simple cheat sheet usually doesn't result in suspension, a school-wide conspiracy might. Your midterm is toast, gone, it was once they found you cheating. The fact that it was a "larger cheating scheme" is going to raise doubt on your performance in your other courses and there's a very good chance that you'll find yourself in summer school because they'll most likely fail you in history all together. Cooperation is your best option at this point.
