On the scantron sheet, fill in your TA’s name (NOT the lecturer’s name) and thecourse number.4. Fill in your NAME and PURDUE ID NUMBER, and blacken in the appropriate spaces.5. Fill in the four-digit SECTION NUMBER.6. Sign the scantron sheet.7. Blacken your choice of the correct answer in the space provided for each of the questions1–12. All the answers must be marked on the scantron sheet. In case what ismarked on the scantron sheet is different from what is marked on the exam booklet, wecompute the final score based upon what is marked on the scantron sheet.8. While marking all your answers on the scantron sheet, you shouldshow your work on the exam booklet. In case of a suspicious activity of academicdishonesty and/or under certain circumstances, we require that the correct answer on thescantron sheet must be supported by the work on the exam booklet.9. There are 12 questions, each worth 8 points. The maximum possible score is8 × 12 + 4 (for taking the exam) = 100 points.10. NO calculators, electronic device, books, or papers are allowed. Use the back of the testpages for scrap paper.11. After you finish the exam, turn in BOTH the scantron sheet and the exam booklet.12. If you finish the exam before 8:55, you may leave the room after turning in the scantronsheets and the exam booklets. If you don’t finish before 8:55, you should REMAIN SEATEDuntil your TA comes and collects your scantron sheet and exam booklet.1Exam Policies1. Students must take pre-assigned seats and/or follow TAs’ seating instructions.2. Students may not open the exam until instructed to do so.3. No student may leave in the first 20 min or in the last 5 min of the exam.4. Students late for more than 20 min will not be allowed to take the exam; they willhave to contact their lecturer within one day for permission to take a make-up exam.5. After time is called, the students have to put down all writing instruments and remainin their seats, while the TAs will collect the scantron sheet and the exam booklet.6. Any violation of the above rules may result in score of zero.Rules Regarding Academic Dishonesty1. You are not allowed to seek or obtain any kind of help from anyone to answer questionson the exam. If you have questions, consult only your instructor.2. You are not allowed to look at the exam of another student.

All cases of academic dishonesty will be reported immediately to theOffice of the Dean of Students.I have read and understand the exam policies and the rules regarding the academic dishonestystated above:STUDENT NAME:STUDENT SIGNATURE:2Questions1.
