Professor Chatham is a very friendly person, and he always sounds very animated and excited in his lectures. He is not the best at explaining topics, but that is also because math 32A is quite abstract compared to single variable calculus/AP Calc. Nonetheless, he's a kind guy and you can tell that he's passionate for the subject. He makes miscalculations during lectures and on practice exam keys often though. His exams are quite challenging, but the practice midterms he posts before the exam often contain questions nearly identical to those on the actual test. His final was a killer (for me), and it's best to pay attention to your mistakes and be ready to tackle challenging questions on a topic that may seem simple. Homework is rather light in this class, but he does assign even-numbered questions to which there are no answer keys to. Overall, I am not entirely sure if I would take this class again, but I do indeed like Chatham's personality. He always seems happy.
