<p>What exactly constitutes a legacy at Columbia, and how heavily do they weight legacies? My grandfather went there for graduate school, will that impact undergraduate admissions? I'm not sure if he ever donates money but he's definitely not a major donor.</p>
<p>Nope. As far as I know you need to have a parent (not a grandparent, though I suppose if it were a grandparent who had donated boatloads that’d be good, and not a sibling) who was at SEAS or CC to qualify for legacy status. Sure can’t hurt though.</p>
