Reviews of professor Nuwan Karunaratne

Rating: 5.0/5, difficulty: 4.0/5
One of the best professors I ever had! He had minimal information on his slides so that you understand without getting overwhelmed. His lectures are 10/10, he is very passionate about teaching physics. I had a lot of difficulty taking similar courses but he made physics bearable and accessible. He will stop and take his time to answer questions.

PHY 107 is hard, especially if you haven't taken a calc-based physics before. You will need to put work in for this class, and Nuwan is definitely your best choice. Great English, and great at explaining. His examples are very good and attending class is quite helpful. Try and do the homework instead of using chegg, that will help with understandin

The best Physics teacher of them all. He knows how to explain the course clearly and knows what he is doing. His course is powerpoint based, but mostly explain the chapters with lots of examples that helped a lot in understanding the course. IClicker are used here.

Literally the best Physics professor you can take. He lectures mainly off the slides but does a bunch of example problems in that help you understand the material. He's clear in his explanations and stops to answer questions if you ask and helps you through problems if you approach him after class or during office hours. I would highly recommend.

His lectures were so conceptual and had few examples so I didn't learn much at all. This made homework problems hard since he didn't teach with examples. Exams were multiple choice but difficult and practice exams were all short answer and didn't help at all. His accent is thick too.

Office hours are very helpful, he spends a lot of time going through the problems for every single student for as long as he is able. Responds to emails well, is very kind in general. His lectures are probably the best of any PHY107-108 professor and he handled the transition to online very well.

Honestly Physics professor is not that great in UB. But Nuwan Karunatre is one of the exception. He made Physics course bearable. The exam format for his Phy 108 class has changed. His exams are open-book/note. I would take him again for Physics 3 if he teaches it.
