Reviews of professor Hasala Kankanamalage

Rating: 5.0/5, difficulty: 3.0/5
Dr. Hasala is the absolute best math professor. Helpful during office hours. He breaks everything down into simple terms. The book was required, but we really did not use it. If you stay on top of your work you will excel in his class. Even though he does not take attendance, you should attend every class.

EASILY one of the best teachers at RWU! I deeply struggled with math and he has helped me understand it in many ways. Everyone says that teachers care wether or not you pass the class, but Hasala actually cares. Takes time to help you understand, actually answers questions, and will give you more examples to help you understand each problem.

Hasla was a really good professor, just not for me. He gives opportunities to fix your objective grades, but he gives one every other week so it's hard to make time to go to his office and fix them. Overall, I recommend taking him for calculus, just be warned, calculus is hard in general and you really need to go to his office hours for extra help.

Hasala is the best math professor I've had at RWU. I've had another professor who was rated really high on this site and he doesn't even come close to how awesome Hasala is. You have to work your ass off but, if he sees you putting in the work, he will make sure you succeed. He encourages people to go by his office hours. You definitely should.

I took his 213 class in the fall of 2023. He is a very nice guy and  is very easy to talk to and is quite flexible for missed tests, quizzes, etc. There were several classes that he missed, but he has just had a baby at the time so I can't blame him for that obligation. He does give opportunities to up your grade, particularly with the final.

My favorite memories from this class was when he told us not to memorize certain formulas because they will be given to us on the test then when we took the test, he gave us no formulas. When we called him out on it, he said it was our fault for not having the muscle memory to remember the formulas. He's ok if you have to if there's no one better.

Once you learn something from him, make sure to have it DOWN. He is very particular with answers, and if he thinks you don't understand a concept, he will decline bonus pts in makeup work. Also do not miss ANY of his classes, or you will feel like week behind in the lessons. Copy the notes exactly or you will be very lost.

I took this class (as a winter term) after taking it with another professor. This is a great way to earn credit if you previously failed/withdrawn. I would not recommend taking this instead of taking a full-term calc. This class was extremely fast but it was managable if you have prior experience.
