Some people like his approach and others hate it. He's definitely more about grasping the overall concepts and so his tests are a little weird. I had him for Chem2 in the summer and we'd have these tests with 5 problems on them worth 20 points each, so if you blew one you were already in the hole. He's not the multiple choice kinda guy. Also, if you're taking the summer course be aware that you may not cover everything. I think we missed out on Electrochemistry, which is an essential for the MCAT.
