<p>Well, I cannot say too much about Case #1 but SAT scores for Cases #2 and #3 seem low (probably a lot lower than their siglings attending H) in the candidate pool. Case #1 did get into Y, so obviously he is well qualified. Without other info, I’d speculate that H (or any other highly selective school) may not feel the need to have two admits with so much similar… of almost everything. Just a speculation, though.</p>
