Not too easy. Not too difficult.
Out of physics 123 and 115, I'd recommend 115 because Brahmia is an amazing teacher and will actually help you understand physics not just memorize it. The only hard part about the class is the Design Practicals and that's about it. There's quizzes online and in class and everything else is easy as long as YOU understand it.
Highlights were the presentations and visual aids during lectures, really helped me understand it. I learned a lot more than I did in high school. From Kinematics to Heat Engines, it was pretty interesting.

Advice for students:
Study and read text beforehand. DON'T go into the class without actually reading the book. Don't rely on notes after class, do it before.
