Reviews of professor Don Mallawa Arachchi

Rating: 3.0/5, difficulty: 2.0/5
He is a good professor but the way the class was organized was inefficient. We have weekly quizzes and tests but there are only a few questions on each, so it's really easy to fail. However, he was accessible outside of class to talk about what was wrong. He even gave us opportunities to retake what we did not pass. He really wants us to succeed.

He does genuinely care that you succeed, and is very available outside of class. The class setup however is terrible. The grading rubric makes it so your lowest graded category (MA, Quiz or Homework) is your overall grade. He reopens assignments several times so you get more chance, and everything is open note. Discussion is not helpful.

I took his Diffeq last semester and had no problem with him. Only exception was the project he gave us which was much harder than the projects given by other professors at Clarkson. Most of the students in my class were really poor in math for some reason. I had taken cal3 so I was good but some of the kids didnt even know the basic derivatives.

He is sometimes hard to understand while teaching but he posts his notes online and the homework teaches you all the material he will grade you on as well. He means well and states in the syllabus to buy the cheapest option possible. Take him for Differential Equations and Calc III

Dr Kumudu is an excellent professor. He knows his subject and explains things thoroughly. I enjoyed his class. He sometimes gives extensions for homework and projects but I personally think that should not happen because its not fair for those who do them on time.
