Reviews of professor Don Mallawa Arachchi

Rating: 5.0/5, difficulty: 2.0/5
You can tell he cares about how students do in his class and wants us to succeed. He built the class so that it would challenge you, but was not too difficult.

Best math professor I have ever had.

He is the best professor Ive met at Clarkson. His explanations are clear and precise. Grading is a bit harsh but fair. Take his course and learn the subject. Never take a course with him if you are looking for a free pass at the end of the semester.

Prof. Arachchi is a great professor. His tests are very fair and his homework is helpful and relevant to the course. He always makes himself available if a student needs help and will even host study sessions the night before a test. You can tell that he cares about his students and wants us to do well.

Had him for calc 3. Pretty good teacher and knows the material. You're supposed to take notes in the pre-lecture and he reviews in class. The beal breaker is most of the pre-lecture videos are more than an hour-long and sometimes they are over 2 hours.
