Grading Information

Other Course Policies


The course will have three mid-term exams and a final exam. The mid-term exams will be given on ????, ???? and ????.

Tests will be closed book and no calculators. Makeups will not be given. In case of documented illness or family emergency or documented University sponsored trips, you will be assigned a grade for the missing test based on an appropriate section of the final exam (that is, the appropriate questions on the final exam will count both toward the final exam score and as a replacement score for the missing test).


Homework will normally be assigned weekly, and turned in at the start of Friday's class.

Homework problems will be grouped according to difficulty. Homework problems marked with a are the easiest problems. Try them for a warmup. If you have difficulties with them, you should reread the section and your class notes more carefully. Problems marked are more difficult, but still straightforward if you keep your wits about you. The problems are the most difficult, and the occasional problem marked will present a challenge to even the brightest students in the class.

Late homework assignments will be accepted, up to six days after the due date. The first late homework will be given full credit. Thereafter, the late assignments will be penalized. The second will be given half credit, the third 1/3 credit, and so on.

Grade Computation

The final grade for the course will be determined by your performance on the homework, the three midterm exams, and the final exam according to the following algorithm:
              Homework        10%
              Midterms        60%
              Final exam      30%



Letter Grades

Letter grades will be assigned according to the following guidelines:
R: < 49, D: 50-64, C: 65-74, B: 75-84, A: > 85
Adjustments to this scheme may be made if there is some operator-error in making up the tests.
