Plasma physics is a really exciting field because of all the advanced technologies that utilize it. Gekelman has been a huge figure in the field for decades so taking this class with him is really a cool experience. He makes some algebra mistakes sometimes, and the slides can get pretty dense with the mathematics, but Gekelman always makes sure to teach the physics of it (it can be easy to get bogged down in the math if you try to write it all down, focus on what he is saying instead).

Make sure youre E&M is strong, and maybe brush up on some basic fluid dynamics, because you really hit the ground running with this class. Overall, a really great class, one of the more difficult classes I've taken out of the physics department.
