Shears Math 121 Makeup Tests

Makeup tests are subject to updates so check back here right before you take a test. If you miss an exam or unhappy with your results of a regular exam, you may be allowed to replace it with a makeup exam. You are only allowed upto two makeup exams per semester. You are not allowed to retake the final exam. The qualifications to take a makeup exam include scoring a 100% on the corresponding unit graded homework in WebAssign or D2L quizzes. If you do better on the makeup exam, the makeup score will replace your original score. Most makeup exams will be given at the Assessment Center (for online and main campus classes) or at the LCC East testing center (for classes held at LCC East only). Each makeup exam is designed to be taken in one 2 hour block of time. Make sure you take care of personal needs and that you have picture identification with you when you go to take the exam. Testing centers generally do not allow students to take bathroom breaks in the middle of an exam.
