Reviews of professor Don Mallawa Arachchi

Rating: 1.0/5, difficulty: 5.0/5
I have him for ma180 right now. The coursework is easy but the design is hard, we have a (one question) quiz every Tuesday so if you mess one part of it up you fail. And we have a (5 question) test every Thursday and if you get one or two wrong you fail. Anything below a 80 is failing.

I enjoyed Prof. Arachchi's Calculus 3 class this semester. I like the way he teaches the material. His exams are on WebAssign and you can score better than in conventional written tests once you get used to them. Exams are very fair. He posts practice tests which are helpful to understand the concepts and to get the best practice for exams as well.

This professor goes in depth and thoroughly explains concepts and problems multiple times in class. The exams are exactly like the practice tests and there are no purposeful curveballs to deduct points. One of the best professors at Clarkson!

Generally an alright professor if nothing comes up during the semester. However, if you have any kind of issue or any feedback (positive or negative) he will not react kindly. Whether it is simply that the wireless internet was not allowing that you turn in homework on time, or you think your test was graded unfairly, he is completely stone cold.

Dr.Kumudu is hands down one of the best professors i've had. He goes over things very well and has many examples for each problem. All the assignments are on Webassign so graded work was returned instantly which was nice. He just overall a great guy

Kumudu is an excellent professor. He gives all the details of solving a problem when he does it on the board. I learnt a lot from him.

Excellent professor! He is by far, if not the best math teacher I have ever had. Very caring and thorough explanations. One who knows the subject and the way of teaching!

Professor Kumudu is awesome! Practice problems are provided before every exam with the exams being similiar to the problems. He was very accomadating during the Covid Pandemic even giving bonus points for effort. Would highly reccomend for Differential Equations or any MA course.

Kumudu is an excellent professor, he does reviews before the exams. If you do the practice exams you'll get an A. Be prepared for the project, unlike the class or homeworks the project is very complicated and lengthy.

He said he would teach this class like the other Diffeq professor, and then proceeded to teach things that even the TA's had never seen before. He gave us a project that was based on a unit that he covered for all of 30 minutes, with the project covering things that we had never learned before and wouldn't learn until we take strengths of materials
