Once you get past the droning voice, Chatlos is a great teacher. His class is pretty hard, but he's always willing to help and makes it really fun. Also has A+ humor.

The only Math Teacher I have had in the last 12 year in the Upper Arlington School System that has made me want to come to class. He makes Statistics fun, and is incredibly helpful - so many people write him off because of both their experiences with math, and his voice, but to be honest, if you actually bother paying attention, his voice is relaxing and he teaches concepts other math teachers could never possibly get into my head.

Chatlos is as knowledgeable as they come. While his class may not be the most exciting, his subtle humor is hilarious if you can find it. His tests are extremely straightforward if you do the study guides, and he is always available before school to help if you need it.

Mr.Chatlos is an extremely intelligent man. Although he is quite his subtle humor is hilarious, and he is one of my favorite math teachers ever. Very helpful (if you ask for it) and made class interesting with "algebrawl" and "blacklight day"

Mr.Chatlos is a GREAT teacher! His class is really hard though.. But he is always there before school so if you ever feel behind or need help, he is there for you. Also, whenever he has quizzes, the day before he has a "black light day". The whole period you work on worksheets with highlighters in the black lights, it's SO much fun!! He was probably my favorite teacher freshman year!

His class is very boring, and you take a lot of notes and then do worksheets. He doesn't explain things to you, because he wants you to figure them out yourself.

Most monotone? Maybe. But if you don't understand something, you should raise your hand for once and ask a question. He'd be glad to answer in depth and meet with you any time. Made statistics a breez

It is easy to get a good grade because of the easy homework points. Mr. Chatlos is very hard to understand. He is the worst teacher I have ever had...he's just terrible and I feel very frusturated.

I don't know how anybody could give Chatlos a good rating. He made me not want to learn the material. Had him 2 years and he drones on. The most boring teacher/prof i have had in 14 years of school

horrible teacher. being a hard worker with respect to teaching is irrelevent if one cannot reach his students. if his peers know him well, how does that make him a good teacher? he is not recommended.
