Professor Stroumbakis has his own method of teaching which will help students learn the subject. In the event you show perseverance and study the textbook you will be fine. Firstly, you might be thrown off by his teaching but when you study and come to class with questions you will learn. Secondly, study hard. Lastly, persistence is key. good luck!

He is the math professor who does teach real math logic. How many of us would still remember the trigonometric formulas years after school? The purpose of learning math never just remembered the formulas, but to develop the skill in analyzing the problem, and eventually solve the problem. So he is the one who actually would show you these skills.

I agree that the complaints don't make sense. This prof. pushes you to understand and some students prefer the easy way. I know because he put us in groups and some students waited for the answers to just come. He's funny and caring and you can learn a lot from him but he's not an easy A
