Mr. Zwanzig is both funny and supportive! He thinks of students as a family and is always ready to help on assignments. I am sad to see him retire, but I have a feeling he will be sticking around the Science Fair program. : )

Mr. Zwanzig is by far the most incredible teacher I've ever had. He is very passionate about what he does, and when he's teaching you can really tell how much he cares about helping his students. His class is very easy and his exams are moderate, but if you don't study they can seem difficult. He is very helpful, extremely knowledgeable, and very kind. He is easy to approach and will readily help with anything. He's basically a student's dream when it comes to science fair. Gotta love the guy!!!

He is a good teacher overall because he will help you get into any college. His class is a little tough because it moves in a fast pace. His tests are hard if you don't study but his class is easy to cheat in, you can use your phone and he just sits on his chair. He doesn't clearify the information. No textbooks what so ever but labs instead. He expects a little too much and gets mad so fast.

Mr. Glenn Zwanzig is by far the most incredible and most knowledgable teacher I have every had. He has guided myself and countless others to a successful future. He has taught me the aspects and nature of science and research. I could go on for years about how great he is but, with only 500 characters this is very difficult. He is a great teacher but further more he is a great friend and amazing mentor.

One of the few good ones left! I want to study dentistry, or something similar, and he has prepared me for that and so much more! I truly am sad Mr. Zwanzig is retiring, but he has made a remarkable impact on Manual! A lot of teachers start to give up, or get a little lazy, when the students do, but Mr. Zwanzig will make sure you learn as much as you can from his class. JCPS, if you let us keep Mr. Zwanzig, we will give you Mr. Baar! Lol, have a great retirement :)
