Shears Math 121/122/126 Makeup Tests Descriptions

Makeup tests are subject to updates so check back here right before you take a test. If you miss a test or an exam or are unhappy with your results, you may be allowed to replace it with a makeup test/exam. You are only allowed upto two makeup tests (and one makeup exam for math 126) excluding the final. You are not allowed to retake the final exam. The qualifications to take a makeup test/exam include scoring a 100% on the corresponding unit(s) WebAssign or D2L graded homework and takehome skills assignments. You may be asked to show me completed textbook and worksheet homework and/or discuss concepts related to the unit with me. The goal here is for you to actually do better on the makeup test/exam. If you do better on the makeup, the makeup score will replace your original score. If you do worse on the makeup test/exam, your scores will be averaged. It is best if you do well on all homework before the original test and all review problems before the original exam, so you can do well and not need to take a makeup test/exam. Most makeup tests/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).

Your test will include all or some of the topics listed in the descriptsions below and it will be a full length test that takes somewhere between 1 and 2 hours to complete.
