There's something to be said of IITs and the way they've done a remarkable job of taking people out of extreme poverty and into (both Indian and American) upper middle classes.
The SATs have initially had this effect in the United States as well: they were initially fiercely opposed by the WASP elite as their immediate effect was to bring "undesirables" like Jews (and later Asians) into what were once the holiest of hollies (Ivy League universities, flag-ship state schools).
Today, however, SATs tend to be too susceptible to cramming: ironically the efforts at making SATs more culturally fair have turned them into reinforcements of existing class structure as now cramming and expensive tutoring become viable strategies.
