Excellent course. My only complaint is that when going through the devices, I felt like it was a bit more fast paced since those in the class were already familiar with the devices. Being someone that only briefly knows about charcoal devices, it was difficult to get through that specific section. In addition, there was no powerpoint PDF for the NJ section. I felt the video was not very helpful in determining many of the differences. A clear list of differences would have been more useful. But overall, the course was well put together and the quizzes were beyond helpful.

I found the classroom environment and off-mike questions distracting, particularly on unit 3, it made the equations much harder to follow than if there were a moving display of proceeding through the equations, highlighting each step as the only screen
