The "15 factors" are behind the WSJ paywall but we can probably guess a couple that weren't already mentioned:
Minority
Household income
2 Parents
I mean really, its just affirmative action V2.0. Im sure if you tick the "minority", "no daddy" or "ate up with social anxieties" then you will shoot to the top of the list. BUT WAIT! That just gets you admitted! Since that student is already laboring under this unfair "adversities", there is no doubt they will not be able to finance their education either, so it will have to become a scholarship! Weve gone full circle but Im just glad everyone is included this time.
