Mr. Greaney is a pretty hilarious teacher. He has some pretty whacky stories. However, if you take his AP World History class, I'd advise you to be cautious. His lectures are only somewhat relevant to the chapter, and he lectures probably 1 day a week. Most of the class ends up sleeping because his lectures are so irrelevant and most of the time, we get through 1 or 2 slides and end up talking about something irrelevant such as politics/economy. If you're taking this, get ready to self study.

Mr Greaney is an awesome teacher. His stories will leave you baffled and his lectures give you great insight to the topic. The only problem is that he teaches you by making you teach yourself.

He is a great person, but he does not exactly know how to teach well. He grades essays very subjectively, and he gives perhaps afew more tests than he should.

Mr. Greaney is a great guy, and he has some good stories, but as a teacher he can be strange. He doesn't demand much, but he doesn't always teach everything that needs to be taught. Tests are hard...

Do NOT take AP World History with him! Does not provide any direction or clarity when you need it. Gives too many tests. Actually a great PERSON, but not good TEACHER.

Probably one of the coolest teachers I've had. Psych is no AP class but he makes it fun instead of rigorous, which is a perfect senior 6th period class.
