His classes are very fast and efficient, I never felt like during any class we were wasting time learning something that was not useful for our assignments or tests. That may be due to the class being online, but Mr. Ian is by far one of the best teachers I've had in some time. He is almost always serious, but when he does crack a joke every now and then it lands or is at least self-aware. I know it sounds like I'm a suckup, but he's just a great teacher.
