Mike Sabatino is his name. He understood math very well and was willing to help those that asked for it. His explanations could sometimes be a bit unclear, but overall he was a good teacher.
He is very confusing when he talks, I usually end up figuring stuff on my own rather then through his explanations.
He didnt explain things well and he would make mistakes while teaching- he made me feel stupid for asking questions - my good mark has nothign to do with him!
