<p>My personal opinion…
Super hooks: being famous, published paper/book (very renowned one)
Major hooks: athlete at D1 school, native-american, published paper (standard one), national award (Siemens, USAMO caliber)
Mid hooks: legacy, athlete at lower than d1 school, other minority, first generation, national award (SciOly caliber)
Minor hooks: research, national award (NMF or AP scholar caliber)</p>
<p>My list is probably incomplete. These are just the hooks that I thought of, but there are definitely more obscure ones.</p>
