Ask questions that YOU want to know the answer to. What good is asking questions you don't care about. If you don't have any questions, then that's fine too. You and your alo will be in contact a number of times.
As far as questions like "how competitive" such and such is, those questions are irrelevant. Unless you're planning on moving to a new district soon, it doesn't matter if it's competitive or not. It is what is is, and you can't change it.
All you can do is the best that you can do. Best grades, best test scores, best leadership skills you can do, etc. You have no say so on what the other applicants do on their application. Just do the best YOU can do.
Hope you don't take my replies as brass. If you look through this forum enough, you'll find I am the BLUNT ONE. I don't sugar coat. Anyone applying to the academy, I RESPECT as an adult. And I will treat you as an adult. Whether you're 15, 16, 17, or 18+.
So don't ask what the average scores are, or minimum requirements, or anything similar. Your mission; if you accept it; is to AIM for a 4.0 gpa on all remaining classes. To get a 36 on ALL ACT tests. To get an 800 on every SAT test. To work your way up in leadership positions in EVERY activity you're involved in; whether sports, band, student government, Spanish club, or anything else.
Do this, and whether or not you receive an appointment, you'll be able to live with yourself knowing you did your best. And it will also prepare you for any college or work endeavors you encounter.
Best of luck. Mike
