Curving: Exams and quizzes will be graded "on a curve"; the curve will be a function of the difficulty of the exam and the overall performance of the class and will be announced after grading is complete. There will be no additional curving at the end of the semester.
Drop scores: The lowest quiz score will be dropped at the end of the semester. Note, however, that no exam scores are dropped; all three midterm exam scores (and the final exam) count in full.
