Syllabus Summary:
  1. Grading
    3 Exams 66% Highest Exam Score 24%; Lowest 20%; Other 22%
    Quizzes 8% These are open book take home quizzes ~weekly.
    Owl + iClicker 8%
    Laboratory 18%
  2. Exam Policies:
    You must have a passing exam average  in order to pass the course - Failing two of the exams constitutes a failing exam average.  An F will be determined by the exam average and if you fail an exam this will be noted in the Owl Grade Book and on the exam itself.
  3. Lab Policies:
    Lab Meets every other week, starting Tuesday, January 28.
    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.
