Sean Hickman is a very professional teacher, more akin to a college professor than a high school applied tech teacher. He has very high expectations for anyone who takes his classes, but he also tried his hardest to help people who are struggling when he can. For the type of classes he teaches, he's close to ideal.
To many who were on lookers he may have seemed like a harsh or sarcastic teacher, but he was neither if you actually applied yourself in the class. He understands that many students join the class to have an easy grade and purposefully makes it so students will not have an easy time. While his exams were difficult to study for if you applied yourself in the lab you had his respect.
good teacher, ran a strict class but had a great time in that class anyway
