Reviews of professor Sam Gralla

Rating: 3.0/5, difficulty: 5.0/5
I enjoyed his lecture style of going over both the theory and example problems which were helpful for the homework and exams. He religiously followed the Griffiths textbook, so it's helpful to read ahead of the lectures to get familiar with the concepts. He's a tough grader and expects you to have a solid vector calc background.

331 is one of the hardest PHYS classes, and Gralla was a solid professor for it. He knows his stuff and the lectures were always good, so you will learn a lot by in class. You may only need the textbook as an extra reference. Grading is tough (90 = A), though I think he did bump the class up 5% or so at the end. Hard to get an A, but possible.

Professor Gralla gives decent enough lectures that I rarely had to use the book. His assignments are very fair in both difficulty and length. Definitely one of the better physics professors in the department. Provides answers to HW which is also very nice.

Due to covid I had to drop his class. He did contact us quickly with his game plan and he executed it well. His lectures were amazing both in person and online. You will either need to attend every lecture and take good notes or read the book to pass this class. He explains things well and thoroughly and tells you when he's used the ratio test

Excellent Insight. One of the greatest teachers I have ever encountered. He made what I thought was going to be a class consisting of a long dull series of problems in Lagrangian and Hamiltonian mechanics into something really worthwhile. We covered some very interesting material students never got with the previous CM professors.
