Both went to Penn Stat in under.
The elder sister went to MIT for PhD in nuclear engineering. Now working in a nuclear firm in NC.
The younger brother took a summer math program in Peking University. Then went to UCB for master. After graduation first worked at Apple in Sillicon Valley then moved to Sealtle for either Google or Amazon.
The moral of the story, Penn State could be as good as very top tier schools.
