Catching stuff is really hard in class unless your'e really good at focusing, but if you ask him later he's so willing to help and explains things real clearly

Dr. O is the man. U can do anything in class and he doesnt care. U can also easily get a B+/A- by doing bad on all tests.

as a sophmore he was awful, but as a senior he was mad cool bc he would always push back quizzes and not have us pass in labs.

You guys are nuts--Dr. O is extremely clear if you pay attention, and knows his stuff *cold, unlike the other Chem teachers in this school. Glad I have him.
