How Did That Happen?

I’ve seen stories that the killer had been diagnosed as autistic at age eight. Assuming that’s true, while he clearly was functioning at a fairly high level, when you hear the stories of his academic behavior at college, one has to wonder–how did he get into VPI? What kind of high-school record did he have?

Was there some affirmative action going on here? (Kind of strange, if so, because usually Asians are disadvantaged by it.)
