Mr. Cosetto was a fabulous teacher. People complain because he's tough, but he really prepares you for university and beyond.

Mr. Cosetto wants everyone to succeed and do well, and gives plenty of oppurtunities to do so. He gives extra credit and bonus marks for students who try hard.

Teaching isn't about being easy. I'd rather have Mr Cosetto who prepared me for university, rather than a person who played games. Thank you so much!

Cossetto was not very welcoming to new ideas or open thoughts, and sometimes discouraged them.
