GRADING

Final grade will be based on the +/- grading system, with weights as follows:

            Highest exam grade: 35 %

            Lowest exam grade: 30 %

            Homeworks: 15 %

            Lab reports: 20 %

Lab reports are graded on a 10 point scale.

ATTENDANCE

Attendance is taken. An absence in a laboratory session implies that a grade of zero will be assigned to the report associated with that session. There will be no make-up labs.  In case of a medical emergency, please contact your TA for instructions.

GRADE APPEALS

Appeals will only be considered in writing. Your appeal should be written in a clear, objective way. Exams may be fully regraded upon review of a grade appeal.

ASSIGNMENTS

For full credit, complete, clear homeworks and lab reports must be submitted by the deadline. Lab reports are due one week after the lab session. Late homeworks and lab reports late no more than three days will receive half credit. Homeworks and lab reports submitted later than three days will not be graded (a zero grade will be assigned).

ACADEMIC INTEGRITY

We value academic integrity in this course. You should be aware of Purdue regulations regarding academic honesty. Any incidents involving academic dishonesty will have an impact on your grade and will be promptly referred to the office of the Dean of Students.
