## Exam Revisions

For each of the four midterms/quizzes (but not the final), students will have the opportunity to redo all the problems on each exam for partial credit. Please follow the instructions below:

• You will typically receive your graded exams back the Friday following the date of the exam. You need to turn in your resubmitted problems by the following Wednesday at 4:00pm.
• If you answered a question correctly, then obviously you do not need to resubmit anything. If you resubmit an answer, redo the entire problem on a new sheet of paper. Staple all your new answers in order on top of your old exam, and hand both your solutions and your old exam in. (I need to see the old exam to compare your new solutions to your old.) At the top of the first page of your resubmission, clearly indicate which problems you redid.
• For each problem you resubmit, I will regrade that problem in roughly the same manner I graded them originally. (The grading might be slightly more rigorous, to account for the fact that you had a limited amount of time during the test.) A new score is computed using your resubmitted problems; if you choose to not resubmit a problem, your old score for that problem is used instead.
• Your recorded quiz score will change by the difference between your new score and your old score, divided by 3. Be warned, you can lose points if your resubmission scores lower than your original answer!
• An example: Alice received scores of 32/40, 20/30, and 30/30 on her exam. Her original score is thus 82. She resubmits the first two problems and gets 38/40 and 30/30. Her new score is 98. She then gets (98 - 82)/3 = 5 (rounded down) added to her original score of 82, and the score that is ultimately recorded for this quiz is 87.
• You can use the textbook or other students for assistance with the resubmission. If you work with other people or consult sources besides the class text, please list them on your resubmission. Also, I will not answer any questions on how to solve problems (unlike HW assignments); however, you can still ask for clarification on questions or allowable theorems/facts etc.
• Notice that if you score high, you will not get very many points by resubmitting problems. For example, if you get 95/100, the most points you can get is 1, so it is up to you whether you want to take the effort to rewrite solutions. You can choose not to resubmit anything at all.
• If you did not pick up your exam in class on Friday, you can pick it up during office hours.
• Solutions to exams will be released shortly after the resubmission deadline.
