Giantatom,
As always, CaptMJ's advice is spot-on. She asks now: "Should you tell your mentor ALO and what would the ALO say?"
First, YES...always tell your ALO your entire plan of attack. Think of this process as a mission to complete; you need a wingman (ALO) to ensure mutual support and protection. The ALO can look at your entire package with you, comment on its strengths and weaknesses, and make recommendations. We're pretty well connected with the admissions folks too.
Now, if you were my candidate, you'd have had the following questions:
1. Your school offers Pre-Calculus but you chose not to take it, why? You answered that above.
2. So, you chose to take AP Statistics because AP Pre-Calculus wasn't offered...okay, why? Why is the AP class more important than the class recommended by the admissions directorate? We'd have had a lengthy discussion about this: is the grade bump of the AP class what you're seeking, or do you have a deep-seated interest in mathematics and you felt statistics was a better choice for you? That's not a bad thing, by the way, but it helps the ALO/Admissions to know you a bit better.
3. Okay, so you spoke with someone in admissions (TEAM BLUE or TEAM SILVER?) and they commented that you hadn't taken pre-calculus...what else did they say? Did they go into any detail, make an immediate recommendation, or explain that they were concerned? Did you tell the individual WHY you chose not to take pre-calculus? Again, a good conversation can go a long way.
4. So...do you "go for it" now or not? Only you can answer that one.
Now it's the ALOs turn.
Okay, so you have a great math background and are taking AP Stat's...that's fine as long as you CRUSH it!! Take the AP exam, score a 4 or 5 on it, and get that to USAFA immediately! That will be noticed! How are your math scores on the SAT/ACT? Are they high? If so, then you're looking pretty good. If they're low...that might be viewed as an indication that higher math might be a problem.
Bottom line: will NOT taking pre-calculus tank your application? NO. Is it a "flag" to some admissions people? YES. However, it's NOT REQUIRED, just recommended. This would have been a great discussion to have with your ALO back in July.
I hope this helps!
