As mentioned before, I'm at Harvard Extension taking pre med courses.. And I was shocked to see how some of my classmates reacted to getting their midterms back and to the professor when debating correct/incorrect answers. Some of my classmates were really getting upset, really raising their voices, shaking, going pale, and making minor threats. For the safety of our instructors, I'm wondering if anyone else feels like security or at least some strong TFs should be nearby during post-exam/grade negotiation times?
