Format Part I: Multiple Choice This section will contain 50 multiple choice questions worth 2 points each. About 35 of them will cover the material since the last exam; the other 15 will be cumulative. Part II: Short Answer - non-cumulative You will answer 5 of 8 short answer questions worth 6 points each that draw on material since the last exam.
