GENERAL EXAM INFO Please pay particular attention to the questions: "What do I need to bring to the exams?" and "What can I NOT have during the exams?" When are the exams? Exam 1: February 13, 2023 (during class time). Exam 2: March 27, 2023 (during class time). Exam 3: May 1, 2023 (during class time). Final Exam: TBA Please make a note of the dates of the above exams because there will be NO make-up exams. You are expected to take all exams. However, if you should miss one exam, you will receive a 0 on that exam and that will be your dropped grade. If you miss a second exam or the final exam (which counts for up to two exam equivalents), this will have a serious impact on your grade. Any student who would like to request a change in exam date (for all students) for religious beliefs must contact their Dean, who will evaluate the situation and make a request to the Instructor on their behalf. Students are required to notify their Dean of any conflict with the exam dates. Any student who is absent from an exam for medical reasons must contact their Dean immediately. An absence from an exam, for any reason, will result in a zero grade; the Instructor will only consider modifying the grade upon receipt of a written petition from the Dean. This means neither faculty nor TAs should receive any requests from you for make-up exams, for changes to the grading scheme related to missed exams, for requests for Incomplete grades due to missed exams, etc. The ONLY communication to faculty on these matters should be from the Dean after you have discussed the situation with your Dean. See the Instructor immediately if you have an “official conflict” (defined in the Bulletin as 3 exams on the same day or two exams at the same time) that prevents you from taking the Final Exam at the regularly scheduled time. If you miss, or expect to miss, the Final Exam for any other reason, you must request the grade of INC (incomplete) from the Dean’s Office of your School (Instructors are not allowed to grant an INC status without authorization from the Dean’s Office). What is the nature of the exams? • The exams will be multiple-choice, with 25 questions, each worth one point, except for the Final Exam, which will be 40 questions. • Each question will have up to five answer choices, labeled "a" through "e," only one of which is correct • There is no penalty for incorrect answers, so it is to your advantage to answer every question What are the arrangements for the exam room? The in-semester exams will be given in 309 Havemeyer Hall at the given dates and will run for the duration of the class. • There will be assigned seating for the exams. You will be able to see your seat assignment in the Grade Book on Courseworks several days prior to each exam. You will not be allowed to take the exam if you are not in the seat assigned to you. • The exams are scheduled to start at the official beginning of the class period so you should arrive prior to this time. What will the exams look like? • Each actual physical exam consists of two things: an exam booklet in which the exam questions are written and an answer sheet—a "bubble" sheet—on which you will enter your answers to the exam questions • The exam booklet will provide space beside each question for you to do calculations, make sketches, or write notes. • The exam booklet will include a periodic table, a page of physical constants, conversion factors, and/or a list of equations that will be needed on the exam. While many equations will be given, you may still need to manipulate these equations into a somewhat different form to do the problems. What course material will the exams cover? • Material covered on each exam will be announced in class prior to each exam. You are typically required to know all material covered in class and/or on lecture slides as well as material covered by suggested homework problems and recitation quizzes unless otherwise stated. What do I need to bring to the exams? • You will need to have your student ID card • You will need to have your uni — entered on the "bubble" sheet to identify it as yours. • You will need one or more No. 2 pencils, with erasers, to use to fill in your answer choices in the "bubbles" on the answer sheet. • You will need the departmentally approved TI-30XS Multiview calculator. You can not use any other calculator. • At the completion of the exam, you must leave the scantron, blue books, and test exam sheets in the classroom. What can I NOT have or DO during the exam? • You can not have any calculator other than the TI-30XS Multiview • You can not have a cell phone, smart phone, PDA, MP3 player, CD Player, tape recorder, or any other portable electronic device accessible during the exam. Any electronic device that you have with you must be stored in a closed briefcase, backpack, purse, etc. placed on the floor at the front of the classroom during the exam. Make sure you turn all cell phones off before placing them in your bag at the front of the exam during class. • You can not have any books, notebooks, index cards, or paper, even blank paper, accessible during the exam. We will supply additional blank paper if necessary. • If you leave the room during the exam, you cannot return. What if I have a question during the exam? Any student who thinks there may be an error in an exam question should raise their hand to attract the attention of a TA. The TA will not provide any interpretation pertaining to an exam question but will bring the issue to the Instructor and any correction, if necessary, will be written on the board at the front of the exam room. How and when will I find out my grade? • Grades will be posted to Courseworks once all the tests are graded. If there appears to be an error in the grading of your exam, please send an e-mail to your TA notifying them of the problem and they will inform you of what action needs to be taken. All requests for re-grading must be received within one calendar week of the return of the grade – this is true also for quizzes; grade adjustments will not be made after this time. • A list of answers will be made available to students. Worked out solutions will not be provided. • A copy of the exam and/or a copy of your bubble sheet can be made available upon request after grades have been posted. To receive a copy, please send an e-mail to your TA. How will my work be evaluated? As mentioned above, there will be three in-semester exams, and one final exam. Of the three in-semester exams, each accounting for 20% of your final grade, the one with your lowest score will be dropped when evaluating your final grade. To determine your score we will be using the z-score (or standard score). https://en.wikipedia.org/wiki/Standard_score The final exam accounts for 40% of your final grade. There will be four quizzes during the semester. These are held during the TA recitations (you can ONLY take the quiz in the recitation you have been assigned to, unless otherwise specified). The quiz with the lowest z-scores will be dropped in the evaluation of your total quiz score. All together your quizzes will account for 20% of your final score. To summarize: In-semester exams 40% Final Exam 40% Quizzes 20% [There is NO grade trading between the different parts of the total grade] -------------------------------------------------------------------------------------------What happens if I cheat and I am caught? Cheating in any form (including, but not limited to, copying answers from another student, talking to another student, and being in possession of forbidden material during the exam) will not be condoned and will be handled in accordance with University policies. The consequences of cheating are severe: your grade will be lowered for any finding of cheating and your grade may be lowered all the way to an F.
