Dec 1   EXAM 3

Dec 13  FINAL EXAM, 2-4:30 in Cox Science 126
 

 Course textbook: Ricklefs, R.E.  1997.  The Economy of Nature, 4th edition.  W.H. Freeman, New York.

PLEASE NOTE: This course cannot be dropped without penalty after Oct. 26.  Students wishing to drop after this deadline must write a letter of appeal to the Faculty Committee on Academic Appeals, 2nd floor Ashe Bldg.

GRADING POLICY:  Course grades will be based on the total points earned out of 300.  Each exam is worth 100 points.  Exam format includes a mixture of multiple choice, true-false, short answer, and essay questions.  Your lowest score from Exams 1-3 will be dropped.  THERE WILL BE NO MAKEUP EXAMS.  If you miss an hourly exam, that exam will be the one that is dropped.  You must take the Final Exam.  Students are expected to do the reading corresponding to each lecture prior to coming to that class.  Exam questions will come from lectures and reading material. Class attendence is therefore expected and necessary.  A grade of "Incomplete" will be awarded only when your instructor is satisfied that there are reasonable non-academic grounds for failure to complete the course.  An "I" will not be awarded to students who are in jeopardy of failing the course.

Please do not ask permission to take the Final Exam at a time other than the scheduled time.

THE HONOR CODE:  Students are required to uphold the undergraduate student Honor Code and will be expected to sign the following pledge on each exam and written assignment:  "On my honor, I have neither given nor received any aid on this examination."  It is the policy of the Biology Department that academic dishonesty or complicity with dishonesty will result in a failing grade in the course.
