Prof. Greenberg is very humorous and clarifies the lecture. BUT, his exams so far are difficult. I'm not kidding. For the first exam, you can memorize and comprehend the first 3 chapters and that still will not help you ace his exam. The questions he puts on his exam are physically torture. I felt like giving him back the test as soon as i got it.

No power points, no leeways, just straightforward old school teaching. He isn't a bad teacher in terms of knowing his material and teaching it but I found the course to be really tough. He also doesn't answer his email or phone.

He is okay when it comes to teaching the material but sometimes he goes too fast. But he is available after class to answer any questions. However, his tests are pretty difficult. The short answers.

If I could give him 0 stars I would. He cares more about cheating than if his students pass or not. Hes rude, doesnt answer emails, and exams which are a third of the final grade often contain material not mentioned in lecture or the syllabus. ALEKS takes a ridiculous amount of time. Avoid him at all costs. Hardly got anything out of the class.

Greenberg is not adaptable any feedback anyone suggests. His teaching methods are outdated & his class notes are extremely unorganized, all over the place and hard to read. He makes it known that he has worked here for many years so complaints about him WILL be ignored. Also the online HW will take you hours to complete and will teach you NOTHING.

Super inconsiderate when it comes to homework on ALEKS... the homework itself was a lot of work and the exams were hard. As much as you try to obtain information throughout the class, it is still hard to learn (obviously my opinion).
