Unlimited attempts on mock tests

I gave every 600-210 online practice test not once or twice but more than that because i am premium member of the mock tests and i had the option of unlimited attempts. I kept on giving the attempts till the time i was satisfied. Implementing Cisco Service Provider Mobility UMTS Networks certification exam was cleared successfully and the credit entirely goes to the practice i did and not just the syllabus i studied.
