Unlimited attempts on mock tests

I gave every JN0-223 online practice test not once or twice but more than that because i am premium member of the JNCIA-DevOps practice tests and i had the option of unlimited attempts. I kept on giving the attempts till the time i was satisfied. Juniper Automation and DevOps Associate certification exam was cleared successfully and the credit entirely goes to the practice i did and not just the syllabus i studied.
