PRELIMINARY EXAMINATION I NAME: ___________________ ID No.: ___________________ PRELIMINARY EXAMINATION 1 - 2005 GENERAL PARASITOLOGY DATE: MARCH 15, 2005 PLEASE WRITE YOUR NAME ON EVERY PAGE. ALSO, RECORD YOUR ID NUMBER IF YOU KNOW WHAT IT IS. Examinations : Each examination will consist of 50 multiple-choice questions, with only a single correct answer per question. Keys will be posted as soon as it is verified that all students have taken the exam. I will change how a question is graded if it becomes obvious from class performance that it was written incorrectly or in an ambiguous manner. Answers are recorded on bubble sheets and graded by machine; I will also ask that answers be recorded on the test paper itself. It is probably going to take me a week to get this back to you, mainly because I will be out of town. I will get it aback as fast as I can. Grades: Each question on each examination will be worth 2 points; thus, there will be a total of 300 points in the course. Your final numeric total divided by 3 will determine your grade. Rounding is performed by the simple method that any fraction over a whole number will be rounded to the next whole number, i.e., 91.009, 91.1, and 91.7 will all equal 92. Grades will be based on the Cornell formula: <60 F, 60-62 D-, 63-65 D, 66-69 D+, 70-72 C-, 73-75 C, 76-79 C+, 80-82 B-, 83-85 B, 86-89 B+, 90-92 A-, 93- 95 A, 96-100 A+
