Retaking the tests jeopardizes my level-diploma?

I successfully completed Levels 1 ( Foundation Training - 2018.3) and 2 (Orchestrator 2018.3), but had to quit my studies for a while, so I want to repeat what I learned from the start. Viewing my previous answers is not a good test of my knowledge, so I want to retake tests. If I fail some, will it destroy my level diploma?

@mmatt no you can download the diploma pdf before taking the test then can attempt the test.
