Just thought I'd throw in that the USAFA is one of the top ten hardest schools to get into in the nation, while ERAU will take just about anyone...
Their US News admissions rating is "selective"....which means you need to scribble out an essay and be in the top 75% of your high school graduating class. I guess my point is: don't prepare for ERAU and expect to get into a service academy. If you prepare for a service academy, you're guaranteed admission to ERAU.
