contradictory opinions

I'm in my second year of Environmental Design and during the first year I've heard many contradictory opinions about the Think Tank course. Some said that the course was extremely unnecessary and a complete waste of time while others told me that the course was very educative and helped to develop their design skills and design awareness... But same problem I've encountered even when entering OCAD and it turned out that all of my classes were extremely helpful and taught me a great deal regardless of what I heard from other students who've taken same courses. And the most interesting part was that the more contradiction there was about the course or the professor the more exciting the class was for me, so.... looking forward for being in this class anyways!!! cheers!
