In high school you will hate his classes but when you get to university you will be very glad you took it. His classes prepare you for University Chemistry
Roger was a great teacher and a great guidance councilor! He's sarcastic + funny if you're quick enough to pick up his jokes-you need to be able to catch on! Prepare to work hard!
He'll push you hard for the first few weeks. Can be a bit sarcastic but pay attention, you'll learn a lot from him. If you're taking a B.Sc. take his Chem12.
