Taking this professor means academic suicide. You wont understand anything from the lectures because of his accent and lack of basic grammar. Everything gets taken off your final grade and there's no way to make it up. Lectures are long, boring, and unorganized. I have taken so many math classes and I never complain but this professor....

No curve, extra credit, or note sheets for tests. Grading is mostly online quizzes and HW so don't stress if you don't do great on the midterm or final. Material isn't harder than Calc 1. The other reviewers make it sound like there is much more homework than there really is. Much of it is optional. Get a tutor and you will do well in this class.
