i have him right now, it is safe to say that he is by far the worst teacher I have ever had in my life! This guy thinks the whole class understands what hes talking about, expecting that we know and remember everything from last year. The amount of times hes messed up and a student has had to fix him is insane. If you want to go to university please switch out. Also, cares way more about cell phones in class than actually teaching us.

really nice and sweet man. you can go up to him many times to ask questions and he will help. He may not be the worlds best explainer but he try's, and thats what matters. You really have to do your homework to do well on his test. but Do homework without understanding what is going on will not help. to do well on his tests you have to understand the concept really well in order to do well in his tests. for that redo problems, get help from outside.

He does not explain. HE understands what he is talking about but fails to realize that the material is new to his studenrs. He gives to brief of an explanation for what should be expected to be taught by a math teacher.

HOLY MOTHER OF THE TEACHERS WHO DON'T EXPLAIN ANYTHING. I have him for gr 11 academic math and frankly, he sucks at teaching. Sometimes he gives us a wkst of the lesson and is like, "There ya go, you should know exactly what to do." When he DOES do the lesson with us, he messes up his own calculations 98% of the time and confuses everyone. The really smart kids actually have to correct him. This would be OK for gr 9 or 10 math, but THIS IS GR 11-THE YEAR YOU CAN'T JUST LEARN FROM THE TEXTBOOK.

OH LORD. Worst teacher EVER. He is SUPER annoying. I mean, he is a nice guy and..kinda weird in the funny type of way? I'm in grade 9 academic math and he is the WORST teacher at explaining things. I either get it wrong or have to teach myself. I honestly dread Second period everyday because of him. He lowered my Math average from a 93 to a 67...thanks. WORDS OF ADVICE: IF YOU HAVE HIM FOR MATH, SWITCH ASAP!!!!!!!

Omg, I've had him every year. Lol. Nice guy, kind of weird in a funny way, can't teach to save his life. He tries though so I gotta give him credit for that. I always do AMAZING in his classes but then again we always skip over like two units. :-p

Nice guy, very strict when it comes to proper procedure and things like that. He's probably really smart but he has a hard time conveying it to students, may want to condsider another chem related job
