I took Professor Mahawanniarachchi's summer online course, and the class was amazing. He makes sure you have everything in order to learn, and excel in his class, he also reachable by email. The videos that are provided are fantastic, and the book used is simple to learn from. He offers reviews and the course isn't heavy in lectures. I would take this professor again if given the chance, as long as you get on everyday you should have no problems passing.

Professor Mahawanniarachchi's class is not challenging if you do the homework. The reviews are the same or closely similar to the test by using same problem. You get an A if you complete the required review. It's a challenging material, but not a difficult class if you take the time to do it. I'm a math major though, so this is bias. However, it's not really a difficult class at all. Don't be afraid of it.
