The knowledge check is a way to test the understanding of reviewed course material.  The Gateway Academy knowledge check supports single choice questions, explanation of answer options, and multiple attempts. 

When designed, a minimum score required to pass is set as well as the number of attempts have to be indicated. If learners can redo the knowledge check until they get the minimum score, then the number of attempts should be set on 0. 

At the end of the knowledge check, if learners fail to reach the minimum score to pass the knowledge check and multiple attempts are allowed, they will be able to redo the whole test. Redo of individual questions is not possible. 

Take a couple of minutes to watch the video below for more details how to set up a knowledge check and how it looks from a learner's perspective.
