A  Fully understands the material covered in class, and in the problem sets; can extend ideas to new situations and more complex problems; successfully combines techniques to solve problems not demonstrated in class; work is of a consistently high quality. 
B  Understands most material presented in class and in the problem sets; correctly applies procedures to problems similar to those demonstrated in class; often successful in combining techniques to solve problems not demonstrated in class; work is of moderate to high quality. 
C  Understands much of the material presented in class, but is weak in some areas; can solve most problems similar to those done in class; sometimes applies ideas incorrectly or incompletely; needs more practice in some areas for full proficiency in the material; quality of work is moderate or inconsistent. 
D,F  Has serious difficulty with much of the material from class and the problem sets; consistently misapplies procedures or fails to complete the solutions to problems, even those that are similar to the ones covered in class; quality of work is inconsistent. 
Generally, I try to produce assignments where the grade ranges are approximately 85 to 100% for an A, 70 to 85% for a B, and 55 to 75% for a C, though this varies from assignment to assignment and from class to class.
To obtain an A in this course, you will need to be able to do most of the starred problems on the problem sets, and all of the unstarred ones. You will need to perform well on the inclass exams and quizzes.
To obtain a C in the course, you need to make significant progress on the majority of unstarred problems on the problem sets, and be able to successfully complete at least some problems on the exams, though you may not be able to do the starred ones.
To obtain a D or F, you will be unable to complete most problems on the exams, and will continue to make serious errors on the problem sets as well. If you are not able to do at least one or two of the main problems completely and correctly on the final exam, you will not pass the course. Turning in problems late (or not at all) and excessive absences from class also can result in these grades.
