Comments on the course

If you took the highest level physics course offered at your high school then most of the content should be review. If did not do well in high school physics then this course will be more challenging as content is deeper and more expansive; i.e you learn mostly linear motion in high school, now we also cover rotational motion.

Advice

Read the assigned readings as soon as possible because he doesn't 'teach' it in class -- rather he skims over it and does examples and thought experiments based on what you should've covered in the readings. Try and get high grades in labs and homework to cover for formal evaluations, since his quizzes and exams are pretty difficult (the questions are usually based off of the challenge questions he puts on his slides / homework).
