2. Exam Mechanics and Scope
The exam covers Lectures 1 – 3, comprising material in Chapter 21 and some selected material from the introductory lecture (see the course syllabus).
There are 18 multiple choice questions. 100% on the exam means 16 questions answered correctly. It is possible to score greater than 100%.
Students are expected to show work on the question paper in order to get credit for answering questions correctly. There is otherwise no penalty for wrong answers.
Circle your chosen answers on the test paper as well as on the Scantron sheet.
Use the back of the test paper if you need more room to do scratch work. For long questions, tell the grader to look there.
Bring calculator & #2 soft pencils for marking the SCANTRON forms.
A formula sheet will be provided. It is at the end of the exam package and is identical to the one posted on Janow’s web site.
Turn off cell phones, pagers, laptop computers, any other communication devices or noise makers.
A suggestion: first work the problems you know how to do, then come back and finish the ones that are doubtful.
Be sure to comply with the Honor Code Pledge.
