While getting my civil engineering degree there were two teachers who everybody tried to avoid because they were blatantly open about wanting to fail as many students as possible. One taught Chemistry II and the other taught thermodynamics. THANKFULLY I didn’t get the jerk for Chem II and never had to take thermo. I remember some of my engineering buddies literally being in tears when they found out they had to take thermo our junior year. Sucked to be them. LOL
My Chem II professor worked for the Russian Government on Chernobyl clean up. She was brutal. She had at least a 15% drop out perhaps more.
