Good professor, there isn't much work to do in this class, and you do learn something. His quizzes are somewhat tricky, but everything is based on a fair curve.

The teacher is not as easy as the ratings says!
His quizzes are tricky and pretty challenging.
As for the effectiveness of teaching, he is really good. He gave us assignments that are really troublesome to do, but you should do it cause there was only 3 assignments during the whole course. He is really concerned about our learnings and even gave out his cellphone number to us! If you are willing to concentrate and learn something, take his class!!
