He sometimes takes too long to get started and can be confusing. He can take the long way around doing a problem to the point that you have no idea what he did. He has passion for teaching and expects passion for math from his students. He is good, if you don't understand, ASK!

HARD, HARD, and HARD. He is not the teacher for you if you need anything explained. If you have a problem, it's not his problem. (as he says) He is slow out of the gate and never really gets going. Maybe he will get better over time, can only hope! Unless math is totally your game, find a better teacher, they are out there.

Mr. Allen is a no nonsense instructor. He's very direct and would not be a good instructor for those that need hand holding. He presents the material clearly and tries to relate it to real life examples. He will answer questions if you ask them. The exam questions come from the chapter review section of the book.

Does he know Calculus? Yes. Is he a good teacher? NO, and I cannot stress how big of big of a NO that is. Rushed lectures, very little opportunities to participate in class examples unless he wants you to calculate something for him with a calculator, and overall, just rude. DO NOT TAKE THIS PROFESSOR. FIND ANYONE ELSE.

Do NOT take this class. If you miss 2 classes, he drops you from the class on the third. If your a minute late it counts as an absence. His grading is ridiculous, and he constantly derails lectures by talking about him and disses other teachers. Homework is optional. He will tell random stories to fill up time, so he won't let you out early.
