★★★★★ Human Anatomy — Biology 351 Final Exam Note: Final exams are not returned! All exam copies will be shredded on the Monday of week #2 of spring term. If you want to see your final exam you must stop into my office to see the exam. However, you cannot keep your copy of the exam. Please print your name clearly on the back of the last page of this exam. Please read the instructions preceding each section carefully. You must answer all questions on this exam. Statistics demonstrate that, on average, between 2-5 objective questions on every exam are ambiguous enough to come out “aberrant” on an item analysis. Therefore, the total number of points possible on this exam is 104. However, grades will be calculated out of a possible 100 points, assuming that 1-2 objective questions on this exam are aberrant.
