nice guy but needs to improve teaching style. He often writes notes and uses a projector to copy off from but frequently makes mistakes and erases all his notes and are hard to follow/does not explain them well. Also he makes a lot of mistakes on tests. (IF YOU WANT TO DO WELL ASK A LOT OF QUESTIONS, SIT IN THE FRONT AND WATCH ADDITIONAL VIDEOS FOR THE COURSE).

Nice guy...
But made a lot of mistakes when teaching which makes it very hard to learn... And was unorganized and uninteresting...
I'm sorry but I do not want him as a teacher again.

Had him for gr 11 physics summer school, I found the course to be difficult because there was so much to learn in a months time. He was alright, everything he taught us was rushed because we were on such a tight schedule (not his fault).

Fantastic teacher. I almost went into chemistry because of him. His teaching style was extremely clear, and he was a fair grader.

Your explanations were confusing and un helpful, and made me hate chemistry. Can't teach, but you're still smart

he's the nicest teacher but somewhat unorganized. I'm sure he is very smart, but as a teacher, its not always easy to understand what he's explaining

I think he should have a job in a chemistry lab. He's obviously very knowledgeable about chemistry but he can't teach it well to a class. He's
