He's awesome. I didn't appreciate it when I was in highschool, but he was so supportive and always made me, a constant skipper and generally bad kid, want to do better. I'm now on my way to law school and I always look back and thank him.
everything on the test was never reviewed in class and his lectures were so boring i was falling asleep 90% of the time. Assigned a PROJECT and a QUIZ during grad weekend. He also joked about cutting his wrists a lot. Not cool, Callister.
He's a great teacher, but his tests ARE SO HARD, OMG.
Very chill teacher with a GREAT sense of humour. Learning biology has never been more fun! He's really understanding and he knows that us students do go through tough times. What can I say? HE IS AWESOME. Super fun to learn from. His quizzes are straight forward, and his tests are a bit trickier where you need to apply concepts but hey! It's all worth it as long as you listen during class. His tests ARE based on what he mentions. =)
Great Teacher, knows his stuff and is excellent at explaining. Has a good sense of humour and will go over things that other teachers will tell you to look up.
He's not your typical teacher, he definitely has character. can even Make breathing interesting. Great at explaining tough concepts, always available to help outside of class time.
hes such a great teacher and u can tell hes a cheerful fella by looking at him. sometime, judging a book by its cover shouldnt carry a bad connotation. It does work
awesome guy. can boost your mark from a C- to a B in 2 seconds. if youre skipping some other class (ex. PE) to study for an exam, he'll let you stay no problem. but only if you have a good enough reason. if you tell him youre not prepared for a test, he'll postpone it for you.
Best biology teacher ever. he has the magical power of transforming the dry text of the bio textbook into lively lectures, and a unusal sense of humor. he likes to diss things to get his point across, which usually makes me laugh. Advices are, pay attention during class evne though its extremely chilled, cause when it comes to test, its not so easy. If you decided to skip his test, be prepared to explain. If you arn't ready to do the test, tell him ahead of time, and he understands. ;) have fun!
I love this guy, hes an awesome teacher overall, and he has a great sense of humour. Rock on Callister! 8D
handles problems and situations like a child! he is a baby a lot of the time and i truly dislike him.
I think he's great. I never really liked science but he is definately making Bio a bearable course. He talks alot but most of it is funny so you dont mind.
He is an AWESOME teacher and is an EXTREMELY nice person. His biology classes are informative as well as entertaining. His tests help prepare you for the provincial exam! Mr. Callister is also very helpful...Be it lunch time, before/after school....he is always there. He is truly the best!
he also teaches PE, and he's really easy-going. he's also quite encouraging
Callister is awesome. He has a great sense of humor that makes Bio class all the more enjoyable. He is creative with assignments and he gets insanly off topic...such fun
he's the best bio teacher ever! his lame jokes are funny and he always gets SO off topic in class
Best teacher ever, funny sound effects, and great jokes. Still manages to give a good lesson with all the insults to other classmates.
I had him for Science 9 and it was really easy. He teaches with a sense of humor.
great! hes really funny and really knows how to make bio interesting !!!
Callister is an acquired taste. You either love him or you don't. Lucky for him, most people love him.
He's cool! Nice, and funny..with his lame jokes. Good teacher, made things very easy to understand! Warning..don't get on his bad side!
he is hilarious... great teacher thought. i really understood everything it taught, and it helps in university!
Great Biology teacher. His tests are tricky, so watch out for those.
