Although the other reviews seem to disagree, Mr. Creelman is knowledgeable and helpful to the point where you could program with your eyes closed after a few weeks in his class. Super funny and a living meme, Mr. Creelman should be worshiped as a god.

Mr. Creelman is pretty knowledgeable in his field. You can give him a problem and he can fix it asap. Unfortunately he isn't good at explaining. His lessons consist of him reading his slideshows monotonously and maybe compiling some program to show us that it works.The way he marks is also slightly questionable. Several people can get 100% on an assignment, but the people he doesn't like will get marks docked off for no reason. TL;DR, can't teach, biased, would not recommend

He honestly knows his stuff, but he really can't teach it to others. I had him for 3 years and hadda drop half way through the semester. He is the teacher you want if you are super serious of proceeding a career in computer software, but not if you want to take the class just to learn something out of it.

Mr. Creelman really knows his stuff, that is for sure. If you are passionate about computer science and willing to put effort into his courses to learn, you will go far. Everyone who rates him poorly is just trying to coast through it. Computer science (especially grade 12) is simply not a course you can coast through. Mr. Creelman also gives up a great deal of his time to help the LCC, and help Lisgar students excel in computer science competitions outside the classroom.

He knows his stuff but if you don't understand or pick up things very fast then it is not a good class for you since his explanations make no sense at all and he isn't even there to help half the time.

Honestly feel bad for the guy...Seems like he knows the material but just can't teach. He tends to be forgetful so be careful when he gives you a mark that you don't think you deserved...He assumes you know the material beforehand, so you will see him skim through the stuff, then expect you to do a test in 3 days. I did not enjoy this class, and so did many other people in my class. Be careful...

One of the worst teachers I've ever had. If you have him for computer science, switch out of his class. He doesn't know anything hes teaching and always uses his "professional judgement" to give out marks. He can't spell anything either and doesn't know most of the things he teaches (forgets). If you ask a question, most likely he won't be able to answer you. A horrible teacher in general, DROP OUT of his class.

Honestly, if you get him as a teacher, I pity you. You won't learn much, and you won't enjoy the classes. He talks in a monotone, and rarely can he keep the class organized and on track. A lot of your mark is based off professional judgement, so if you're brilliant much not a good student, you might not get as good as a mark as a student who's decent but sucks up much more to him.

If you don't know math, change teachers. He cant control a class very well. Mr.Creelman to me was well suited to be a teacher, because he is not very clear and good at conveying a message or idea.

He means for the best and really isn't as awkward as most people think he is. However, he marks a bit too harshly in computer science and does not have the same standards of marking for different stud

I think Mr. Creelman is an amazing teacher. Even though it is hard to sometimes get what he's saying. I have him for computer science, and while you do need to self-learn a lot, that's how it's done!

Quite strange character. Plenty of stories about him, it's remarkable that he has the "I'm so scared" look in his eyes whenever he's talking to a student.

I have Mr. Creelman for Math I have it in the infamous music storage room. despite his faults, he is a cool, kind guy, and so delightfully odd. i am always cheered up by his nice, and slightly eccentric personality. :)

He totally hates me... He blames me and moves me around the class for stuff I haven't even done yet. Also, he never explains anything then tests you on what you don't know every week. It gets annoying after a while, I'm still just understanding now what we did a month ago. On the bright side, what he thinks of you has nothing to do with your mark. Im totally owning his class despite everything.
