Sometimes funny but only because he makes no sense. Hardly speaks English. His idea of a lecture is to read the chapter from the book. Not helpful at all. Stay home and read the book, you'll get the same amount out of the class.

Very nice teacher; very helpful! Such a great man!! Funny way he says DIVIDE! :)
