Dr. Su is a friendly instructor, dedicated to seeing that his students succeed in chemistry and in their academic careers generally.

Dr. Su was my instructor for an online section of Chemistry 40 in Fall 2007. I found the online format excellent, a very efficient way to take a science class. We met once a week for our lab session. When we had quizzes or midterms, we took those in class before starting our lab. Otherwise, the class was conducted online. Like most students, I found Chemistry 40 fairly difficult. The class doesn't require a huge amount of time, but it is important to spend time on it regularly and to keep up with the reading. The attrition rate is high. Be persistent if you're trying to add the class. Chem 40 may be full at the beginning of the semester, but it probably won't stay that way.

Dr. Su is a hardworking instructor. He was online frequently, so there was never a long delay in getting a response to messages sent to him. He always made an effort to accommodate students. The previous edition of the textbook is available for a fraction of the price of the current edition, for example, and Dr. Su indicated reading assignments for both editions. The online class assigns problems on a the Mastering Chemistry website (MCWeb), which only runs on a Windows platform. For students who don't use Windows, Dr. Su provides other problems. He was also attuned to the fact that some students are taking chemistry for general education requirements. He knew that they might not have the time to get an A in chemistry, but he emphasized ways in which they could benefit from the study of the subject.
