Lectures: Reverse lecture style, where you watch lectures on Youtube and he does examples in class. The lectures are from Hopkins, who is a mechanisms expert in his own right. He's got good lectures, and depending on your preferred learning method, you may or may not enjoy it. I highly recommend attending Matthe's supplementary lectures as the examples he goes over are similar to homework and exams.
Homework: Not too long, 3-4 problems per week on average.
Discussion: Because of the reverse lecture style, the discussion takes up one of the lecture spots. Definitely go to the discussion, the TA will go over problems ripped straight from old exams. If you're resourceful you can figure out how Matthes likes to structure his exam questions.
Exams: Like the homework but slightly more difficult, with longer questions. Nothing unfair but there are a lot of topics.
Project: The best and worst part of the course. The design problem itself is pretty fun. If you get a good group it'll be pretty straightforward, arguably pretty MATLAB heavy but not bad. If you get a bad group you'll find yourself shouldering a large portion of the work alone. In addition, the groups are 10 people, so unless you somehow have 9 friends taking the class with you, you're going to have a few slackers. Good luck!
Overall: Don't get complacent and think this is 102 pt.2. While in some ways it is, it's a bit less intuitive if you don't practice. Make sure to keep up with both recorded and live lectures. If you fall behind, it's hard to learn the material all at once, as there's a lot of nuance.
