Aviation selection rates are not school specific. The things considered are ASTB score, GPA, class rank.
ASTB 7+ across the board is strong, 8+ almost a lock (if no Nuke draft).
GPA in a Tier 1 is irrelevant. You get a multiplier that overweights a 2.0 over a 4.0 tier 3.
Class rank is where is gets interesting. If your unit knows how to play the game, should be irrelevant.
The game is ranking current graduates over off semester graduates. Most units do this.
If not, it won't matter if you're a tier 1, with an 8+ across your 3 scores.
