I'm pretty sure Kolasa was the reason I aced Bio 1M03
His exam questions were great. They were very fair if you understood his slides. Not very tricky from what I can remember.
I was planning to take this course in 2013-2014, but changed my plans when I saw he was teaching. However, after reading reviews on him from when he taught this course, it didn't seem like a very good idea. I decided it would be wise to drop it and wait to see what happens this year.
