they certainly didnt round em up from my corner of the world...
there was a herd of em in chem engineering classes...
Back then, I took a lot of my junior year general engineering classes (ee major) at night because they tended to be taught by working engineers who knew their subjects better than the professors. The night classes were filled with Iranians looking to maintain their student visas and avoid being sent back to the ayatollah's hell hole. They were disruptive and immature and it was pretty obvious that education wasn't foremost on their minds.
