They will get taken back to the beginning once they click on the next button on the Review page when they fail, correct? I think that is the standard logic. If you include a results page, the user will be taken there first so that they know how they did on the test before executing the next action of go to page on pass/fail.
If you don’t want a failed user to get to the results page, then you would just need to create your own page for success (congratulations, you passed at 100%), and if failed the user will be directed to the beginning. So probably best to remove the standard Results page.
