Instructions: Answer all questions on this page. Suggested working time: 70 minutes. This practice version uses one point per answer field; the original paper exam uses different scoring. Round final answers to two decimal places unless the question says otherwise. For realistic practice, work without the reference sheet and use a scientific calculator. For study, the conversion tables and formula sheet is available. Your answers stay on this page until you submit; they are not sent to the instructor or saved to a server.
