1. APEC3001 – Second Review Session Marc F. Bellemare Fall 2015

2. Structure of the Exam Four multi-part questions No huge surprises: Everything on the exam (save for bonus question) is stuff I discussed in lecture/similar to book problems. 60 points -> 75 minutes. Budget your time wisely, and you’ll have an extra 15 minutes at the end. Don’t leave anything blank.

3. Structure of the Exam Non-scientific, non-graphing calculator OK. Everything else (scientific, graphing calculator, phones) is NOT OK. Mixture of more technical and essay-type questions. Maybe some true-false questions with justifications, maybe some definitions—I want to reward all types of learner. Don’t leave anything blank.
