Reviews of professor Hasala Kankanamalage

Rating: 1.0/5, difficulty: 5.0/5
Professor Hasala is extensively knowledgeable in calculus; however, he lacks the ability to effectively teach his students who are not gifted mathematically. He was a very nice professor, but not the one to pick if you want to genuinely learn the material. Also, missed many classes my semester and rarely made-up instruction time, leading to issues.

While I understand where Hasala was trying to go with his teaching methods, they only worked well for students who already had an extensive knowledge of calculus. His method of only teaching by examples made the material very hard to learn. Sometimes there would be one example on a topic and then a question on it on a three question quiz or an exam
