Jason Harlow is caring and passionate, he is a very likable guy, however, the course was formatted poorly in my opinion. The textbook was absolutely horrible, and hardly any practice questions were assigned to prepare you for the tests and exam. Good luck in this course if you don't have an extensive physics background, you're going to need it.

PHY196 was a very enjoyable seminar class. The content was interesting on its own, but Prof Harlow's lectures provided extra insight and information, plus the participatory aspect of the class was helpful in clarifying and solidifying our learning. He's a great and funny prof.

The format of his test are really bad (1 question at a time and no going back). It makes it really hard for students to score well on the tests even when they completely understand the material. Even upon complaining and explaining how this method of test taking isn't effective, he just told us thats just how it is.

Harlow is very passionate and friendly. The tutorials are mandatory but deadly boring. Weekly teamup quizzes and assignments are generally quite easy, but then the exam is a bit harder to balance out. Harlow can take a while to reply to emails. You don't have to buy a textbook.

Clear effort to make the class fun with lots of demonstrations - however, seems to be too much focus on that aspect and not enough on the quality of the lecture. Didn't think it was possible but lectures made content even *more* confusing. Make sure you know where to find help.

He made it hard to understand basic concepts of physics. I had a medical emergency and he was not understanding of my situation. Lots of heavy assignments and useless in class examples that made it harder to understand course material. Overall, really bad professor, I would not take another class with him for sure.

Harlow was entertaining. He stays on top of modern social media, like BeReal, Snapchat, etc. He also dressed up as Boba Fett during Halloween! I found his lectures difficult to follow along with, and he doesn't explain key physics concepts well. I find he lacks some substance. It doesn't seem he understands fundamental physics principles deeply.

He's great. I really do hate physics but I found him entertaining and enjoyed attending his lectures. Lots of demonstrations to keep us engaged. He's pretty funny and laughs at his own jokes which makes him more funny. This class is a lot easier if you have high school physics background, though. He posts detailed solutions videos on youtube!!!

I found that professor Jason Harlow was obvious and concise in his lectures, however, some of the tests given in this class were unfair. For example, in our first and second-term test, the free-response dragged people down by 10% by TAs who did not know how to grade properly, affecting my test score.
