Grading Policy

                                                                   

In-class tests.  Six tests are graded by grader, and each test accounts for 10% of the overall grade for the course so that all six in-class tests account for 60% of the overall grade.

 

Home assignments. Six home assignments are given. Home work turned in after 1:55 p.m. on the due date is not accepted. Homework is graded by TA, and each assignment accounts for 2% of the overall grade for the course so that all six home works account for 12% of the overall grade.

 

Final exam is comprehensive and accounts for 28% of the overall grade for the course. Problems on the final exam are of the same level of difficulty as those on the home assignments and tests.

 

 

G = 0.1(T1 + T2 + ... + T6) + 0.02(HW1 + HW2 + ... + HW6) + 0.28F

 

G = Overall grade for the course; T = Test grade;

HA = Home work grade; F = Final exam grade
