You're asking two unrelated questions. But to answer the first, I think most people would think it's pretty obvious. In most of the "Standards" mentioned for applying to the academy, people discuss being the "Top 10%" in the categories. Top 10% of your class; ACT score, leadership, etc. To be in the no brainer category, you'd have to be the best of the best. Of the 10 nominees on your MOC's slate, you'd have to be the "Best". The #1 nominee. Out of the 10,000-12,000 applying to the academy, where approximately 10% receive an appointment, you'd need to be the top 1%.
1. 4.0gpa unweighted. ACT Scores each subject in the 30's+ SAT scores in the 750+
2. ALL AP classes; the IB "Program"; ALL Honor's classes
3. Ranked #1 in your class
4. National Honor Society and school representative
5. Play in 2-3 varsity sports for 2-3 years
6. Captain of 1 or more of those teams
7. Class officer
8. Boy/Girl's state
9. 2 or more additional extra curricular activities; whereby you're a "Leader" in those activities
10. 200+ Volunteer hours
11. CFA scores at or near the max
12. Diversity experience via work or social activities
13. Public Validation of achievements such as All State/Conference, elected official at Boy/Girl's state, school academic awards, community recognition, etc.
14. Stands out above all others in their ALO and MOC interviews. Is mature beyond their years. Is their "OWN PERSON". 100% confident without crossing the line to arrogant.
15. Generalized; this is the individual who (Money aside), can and will usually get accepted to ANY SCHOOL that they would apply to. If they applied to 10 universities from STATE U to Harvard and Stanford, they'd most likely get accepted.
This isn't an all inclusive list. Each individual has different opportunities available to them. There's no guarantee of anyone receiving an appointment. However; there are some, that when you look at their application, class schedule, grades, tests, activities, leadership, etc. they aren't just "Good". They aren't even "Great". They are the "BEST". All applications are SCORED with points. Each area gets points based on their level. The No Brainer isn't a "TOP PERCENTAGE". They are the "TOP INDIVIDUALS". They're the ones that you have a difficult time looking through all the scores to find someone with a higher score. If the maximum score is 1000 points; and the AVERAGE of the 1200 appointees had 850 points; the bell curve will have some roll lower than 850 and some roll higher. The no brainer is probably sitting with 950+ (Assuming it's impossible to get a perfect score).
There isn't anyone on this forum who looks at your actual application and file. Therefor, no one can say if a person is a "No Brainer". Even if you list all your grades and activities, that isn't enough to know. The No Brainer can also change based on the competition. But it's the ENTIRE PACKAGE. I've personally seen 4.0gpa students, with 30+ ACT scores, be rejected from the academy. I've also seen 3.2gpa with 28ACT scores receive appointments. But those aren't the No Brainer packages. They are part of "EVERYONE ELSE". The no brainer is pretty obvious to the academy when they are reviewing applications. But please don't start listing yours or someone else's accomplishments and want someone to say "Yes, you're part of the No-Brainer club". It's the WHOLE PACKAGE. I've been helping applicants to the academies and ROTC for about 10 years. People like Flieger has been doing it twice as long if not more. In my time, not just in my state, I have personally met 5 applicants I considered in the No-Brainer club. All 5 received appointments. 2 accepted the appointments. The 3 others chose civilian schools. But half of the package is what you don't see directly on scores. It's what's written in the ESSAYS. It's what the ALO Writes. (ALO's CAN'T get you an appointment, but they most definitely can PREVENT you from getting one.) It's what your teachers write in their online recommendations.
Normally I say I hope this helps. But this is a question that is looking for definitive points. Basically; fill in these blocks and you're guaranteed an appointment. (Hence: the No-Brainer Club). Well, it's not that simple. There is no magic list. It's like asking kids if their parents love them. They say; "Yes, of course". You say; "Prove it". ...... How do you prove it? Because they feed you, clothe you, house you? Sometimes, you "JUST KNOW" that they do. Same with the no brainer applicant. When the board looks at the application, they say: "THIS is the application that all others are measured by". Not just because of the scores, but because of all of the other aspects of it. Remember, the military and the academy are NOT just looking for the brainiac. They aren't just looking for the Super Jock. They aren't looking for the kid who "Says" they've wanted the academy their whole life. They are are looking for the whole package that they believe they can train into being military leaders that don't "Believe" in a certain lifestyle, but "ARE" the ingredients OF that lifestyle.
