Syllabus Summary:
  1. Grading
    3 Evening Exams + Final Exam 70%
    (Highest Exam Score of All Exams 20%; Lowest 14%; Other 2, 18% each)
    PRS and Owl 10%
    Laboratory 20%
  2. Exam Policies:
    You must have a passing exam average in order to pass the course. 
  3. Lab Policies:
    You must complete all of the laboratory experiments to pass the course.
  4. Academic Honesty:
    You will abide by the academic honesty policy of the campus.  I expect you to do your own work on exams and labs.  You mush flush all calculator memories of any chemistry information before coming to an exam.  You MAY NOT bring any additional materials to exams other than a pencil, calculator, and your brain.  I take honesty very seriously.  
  5. Grade Cutoff's:
    >90's  A.                <55 F
    The other grade cutoff's will be determined at the end of the semester.  However if you want to be assured of a B you should be in the 80's and 70's for a C.
