Very, very good teacher. Explains everything everything and associates Chemistry with the real world. However, his tests are EXTREMELY difficult. He teaches AP material in his regular Chemistry class. However, he doesn't give too much homework, has a decent amount of extra credit, and has various other assignments (lab reports, homework, projects, etc..) that are easy 100s and can boost your grade

I took AP Chem my sophmore year, and despite it being one of my first AP classes I thought it wasn't too hard. It is absolutely necessary to pay attention to his lectures, understand how to do the homework (even if your partner does it), and read the corresponding chapters more than one day before the test. If you do those three things, chem will be easy. In his lectures he sometimes stresses things that hardly show up on the tests, so make sure you study everything to some capacity.
