Allowing users to review and correct test question before submission

To conform with WCAG 2.0 3.3.4 Error Prevention, “for Web pages that cause legal commitments or financial transactions for the user to occur, that modify or delete user-controllable data in data storage systems, or that submit user test responses, at least one of the following is true:

Reversible: Submissions are reversible.
Checked: Data entered by the user is checked for input errors and the user is provided an opportunity to correct them.
Confirmed: A mechanism is available for reviewing, confirming, and correcting information before finalizing the submission.”

When you are developing tests in Lectora, be sure to provide a means for users to check their answers and correct their responses before submitting the test. Verify that questions do not have a limited number of attempts enabled that can prevent users from changing their answer once those attempts have been exhausted. Check that navigation within the test allow users to navigate both backward and forward to allow for a full review of their answers prior to submission. Finally, be sure to give users control over when a test is submitted, rather than automatically submitting the test. In this way you will be complying with Guideline 3.3 Input Assistance: Help users avoid and correct mistakes.
