Although I appreciate your willingness to do so, it is not necessary. Please try to ask questions in class that are precise, thought out, and pertinent to the topic at hand. If you would like to pursue discussion with me that is more wide-ranging, please feel free to visit my office. Do not harass the assistant or otherwise make their life miserable. This will not be tolerated.
Final examinations are always cumulative.
Consequently, I will be unable to tell you what grade you must get on the final in order to pass the course or to get any particular grade since it depends on your relative ranking in the class as a whole. So, please, don't ask this question. Please contact me at my university office, phone me, or leave me e-mail if you wish to discuss something. As I sometimes work at home, make sure and use e-mail or voicemail if you wish. I hope you enjoy any courses of mine that you might take.
