You won’t regret taking Prof John!
He makes everything clear and easy to understand and I definitely wouldn’t have passed 220 and 308 in the same semester if it wasn’t for him.

Taking John will honestly make your life so much easier.
He’s an awesome teacher, explains really well and knows exactly what to focus on. He will make sure you feel confident about a subject. I definitely would not have done well in some of my classes if it wasn’t for him.
-Gabby Bright
The best one ever!!
I took 2 courses comm 305 & 308 with John and honestly without him I wouldn’t be able to pass and understand the courses.
-Natalie Alsaddi
100% recommend!!
A committed prof that actually listens to his students and who actually cares about his students. I would have never passed classes without his help.
-Harman Ramgharya
Best guy!
Didn’t go to one class or open the textbook and ended up passing the class with a B. No idea how but with John K anything is possible.
-Alexandro Cassella
100% take John's crash courses
If you're enrolled in JMSB, you should 100% take John's crash courses. I would go as far to say that Concordia would be better off firing all their accounting, finance and econ profs and instead insist that students take John's crashs + mock exams
