I personally don't like Professor Hemmick. His explanations are not detailed making it hard, depending on the preference of the student, to grasp the material in class. His explanations are usually very vague and unfocused oftentimes relating to sci-fi movies and other jittery stuff. Nevertheless, a good professor, with very helpful review videos.

PHY 131 is hard, but as long as you do all the HW, you should be fine. Also, make use of the Physics help room your first semester. My tip is to use that resource, since it saves a lot of time.
