The time to be concerned about poor performance is as soon as you realize there is a problem. It is fine to ask for help on ways to improve your grade while there is still time left, but don't expect to undo a whole semester of problems just before the final exam. I will return all your work to you after I have graded it, except for major exams. I keep all work you don't pick up for a period of 12 months after the end of the semester. Please talk to me any time you are concerned about your performance in the class.
Students have the right to know where they stand at all times.
If you ever think that I have made errors in computing your grade, please let me know. I'm always happy to explain with you on an individual basis why something was graded the way it was. You can check your current grade on the web at a special web site designed for that purpose. You will receive your password by email shortly after the course begins. You will find more information on how to interpret your grades in the course syllabus.
