The purpose of the post-test is to assess your knowledge and verify your understanding of the topic’s concepts. However, the purpose of the module is for your educational benefit. Therefore, you are allowed to take the post-test twice, if needed.
If after taking the post-test the first time and you are not satisfied with your score, you may go back and focus on those areas in the module where you missed questions and review the content. You are then free to take the post-test a second time. It is important to note that if you choose to take the post-test a second time, your score for the first attempt is wiped out and the score of the second post-test will be recorded for the module.
