I actually feel like he respects me as a human. Knowledgeable, unbiased, teaches well, funny, and knows exactly what he's doing, even if a bit impatient. Excellent classroom atmosphere and command of classroom, as well as easy to understand. Would recommend him, 100%.

One of my best teachers. Although I now remember little of what I learned, I remember once he was helping me after class, and after hard mental effort, that complicated physics equation just opened up to me, like a flower opening its petals. Easily the most transcendent experience I had in a classroom. And since I was the only student who came in for help that day, he put that equation on the final test. Occasionally he'd give us beneficial life advice. A clear, kind, and dedicated teacher

A good teacher, though he tends to have mood swings from time to time. Typically a very charming man with a bright personality, but upon occasion he can be extremely irritable, impatient, and intimidating.

Mr. Z is a great teacher and person. There are a lot of ratings here for Mrs. Z which skewed the averages for Mr. Z negatively. He is definitely a 4.5 teacher.

Very strict, but in a good way. Gives extremely detailed explanations for subjects discussed in class, and even doing experiments to demonstrate them. Really cares about the student's education.

I felt like we had to learn a lot of the things on our own, but she emphasized during classes the information that she wanted us to know for quzzes and tests, so the class was very easy. I liked the notes that she gave us, and I thought she was a pretty good teacher. She didn't overload us with homework and her tests were very reasonable, if not a bit too easy. Class was boring sometimes, but I loved having Mrs. Z. She's a great and funny person. I wish she taught higher level science classes.

If you are a new student, she expects you to catch up on your own. She does not teach, just assigns you to read the hw and you are expected to learn through the hw. Chem with her is hard. Although, even though she can't teach, she is a very kind person :]

nice teacher. the classes are easy when you pay attention. She does her best to answer questions and teach as much as possible. however, if you are talking she stares at you until you stop and then by then everyone is quiet and she says "are you done yet" just to humiliate you or something. once she did that and when the student became silent mrs.z was like "are you done yet" and the student said "ya" and then mrs.z was like "THOUGH SO!"

She's a pretty cool teacher. She gets to know her students and is really fair. Her material is easy to learn, and she makes it easy to memorize. Her quizzes and tests arent hard as long as the students have listened in class.
