PHYSCS31 . Guruswamy S 14 Years Ago

Very good teacher. Very friendly, willing to answer questions, and knows quite a bit about physics. You just have to show that you're interested in the subject, and everything is great. Tough class, but she has the greatest accent and the class is fun

Phys100A . Guruswamy S 5 Months Ago

Let's address the elephant in the room: Physics 100A is hard AF regardless of professor. Period. Dr. G is a really good professor that tends to be more square on bureaucratic stuff than other professors, and her lectures are rigorous. Tests and HW are very hard, but what else do you expect? Good luck on your first upper div physics here at UCSB!

PHYS21 . 1 Year, 5 Days Ago

Though sometimes the explanation are a bit abstract and hard to understand, but he's accessible outside of class, so I can still understand most of the contents. Also, the homework and test have reasonable difficulty, which the class is enjoyable.

PHYS23 . 1 Year, 1 Month Ago

Excellent professor! Occasionally went a bit slow in lecture, and the homework was much harder than the quizzes or exams.

Great professor, not much else too say. You should expect a lot of work is Physics 20 series regardless of the professor.
