Prof Musumeci is great. His love of soccer and his accelerator "downstairs" is so funny. Lectures are very enjoyable and he is willing to stop to answer questions. The HW are hard (even though they are straight from Marion and Thornton which has a solution manual) because sometimes I can't even understand the solutions. The exams are timed for an hour which is stressful with the online format because sometimes you get unforeseen tech issues. The questions definitely hard, but at least our atrocious average (40 something percent on the second MT I think?) got curved in the end.
Beware, this class does have a 2-hr mathematica lab section that is not shown on the schedule and mathematica hw was 10% of our grade (mathematica was also on the second MT). It's not too bad though because you don't really have to go to the labs to complete the assignments, since Corbin posts his notebooks after every lab.

Great professor. He clearly cares about his student's learning and can be funny at times. His lectures are clear and he explains things very well. The homework often took a long time but I felt the questions asked were relevant to what would be on the midterm. The sole exception to this was Lagrangians for me since the homework questions felt leagues easier than what was asked on the midterm. His tests are HARD, though, and I had difficulties completing them within the time limit. The average for the first midterm was ~70% and the average for the second was 48%. There's also a Mathematica portion to this class but it's nothing too bad (only 6 homeworks in total). He also gave two Mathematica projects as extra credit.

Hands down, one of my favorite upper-div professors. The material is difficult (105A and B), but he explains it pretty well and assigns very good homework problems. I like how he doesn't bother with really bullshit topics. He'll ask fair questions on the midterm that are homework-difficulty, so if you can do the harder homework problems without the solutions manual, then you'll do well. Take him if you can; I wish he taught all the upper-div physics classes.
He's also hilarious and nice and seems to enjoy the class as well as his students.
