Dr. Herman Lam graduated in June 1972 with a 3.8 in EE & last seen was a Computer Science prof at U of Florida in Gainesville. As one of my old roomies Meade Sutterfield, a 3.4 BSEE grad & Harvard MBA says, Herman played FB or ran track and studied. That's it. He was either at some sort of practice or he was studying, unlike yours truly who followed the "anything more than a 2.0 is wasted effort" approach - $1.25 pitchers at nearby bars didn't help either.

We did indeed have a lot of IMs...... most wannabe engineer S-As found Bud Carson's then-unlimited practice & meeting time incompatible with high academic prowess. But we did have our share of Civil & Industrial Engineers.
ROTC was another time eater. Only so many hours counted toward graduation, but it ate three hours in the classroom & one on the drill field every week just like a chem lab. Another roomie, a 3.2 IE GT grad & Harvard MBA, had his roughest go with AF ROTC classes.
Obviously time management was the major takeaway, not the actual knowledge derived from my major, Textiles Management.
