Absolutly awsome teacher if you actually want to learn something. If you want to be spoon fed, don't take him he won't spend extra time with slackers, but if you are really trying he will do anythng to help you understand it.
awesome teacher with incredible insight into math in general
i quite like Sammy's teaching methods, he is always sure to ask the students if they understand what is being taught, and has not yet rushed through any of the course. very helpful also.
Unhelpful, and seemingly uncaring about student progress. Little patience
