I asked for a 94 in the class and he gave it to me. Maybe it's because I got an 85 on the final, which is really good considering you can get negative grades with this guy.

He's very smart and knows his stuff but he doesnt really understand the teaching role where he has to teach us that knowledge. Its hard to learn somethin in tat class but if u work hard and study for his tests and 4 the regents u will do good. He gave me a 90 and tat felt like a major achievement. DONT TALK BACK TO HIM AND U WILL BE FINE. just remember tat and maybe u will do good in his class

JUST PLAIN BAD. he uses old fashioned methods of keeping a classroom "under control" (meaning he yells alot) and it doesnt even work! worst of all WE DONT LEARN THAT MUCH. he's smart, ill give him that. I have no idea why he became a teacher, its not like he cares about students wellbeing anyway. and another thing: he is so paranoid. im gonna sneeze on him one day.

Everyday afterschool i have the biggest headache after his class. i recommend you buy ear plugs if you have him. if you don't one day your brains would pop out from all that screaming. And don't get me started on the teaching. I learn absolutely nothing in his class, except how ot take care of a big headache.

Overall a good teacher but needs to learn the meaning of self control. If he'd quite yelling at everyone, they might actually like the class. Tests are fairly easy, especially multiple choice but the answers to the biggest questions are usually discussed only once... Annoyingly bad sense of humor.

Why not try teaching and stop disciplining the students. We can be just as good as we can be bad.

he's ok as a person, i actually find his blantant sarcasm funny. but as a teacher-he's not one. he never teaches you anything and if you ask him for help (even though he tries), he goes into the history of the world before reaching the answer.

He is a nice guy, and knows his chem, but doesn't teach in class. Learn what you can from the book... for AP... what can I say... only 30% passed last year.

He may be strict, but that's his style. All I can say is that it works, and he warms up towards the end of the term. Just listen to him, and you'll pass the AP.
