Because I am approaching the end of the book, I have decided to go back to the conspiracy theory that Dink first mentioned to Ender. When Dink first brought up that Battle School is only there to keep the I.F. in power and that buggers were not attacking, Ender, for the most part, believed him. I also thought this theory sounded reasonable. As the story continues, however, evidence for and against this theory arises. At one point in the book, Ender says that the real enemies are the teachers and not the buggers. I think at this point that Ender is fully convinced that Battle School is a fake. Then, evidence arises against this theory. The first piece of evidence is when they send Ender to Command School. If Battle School and the buggers were not real, then the I.F. wouldn't bother to send people to Command School, because they could stay in power without having a Command School. Another piece of evidence contrasting Dink's theory is Mazer Rackham training Ender. Mazer Rackham has fought the buggers before, and he wouldn't take the time to tutor Ender if the Third Invasion was not real.
