Hi Vishal,
More than 4 days have passed since you posted your question, and I am just wondering what could have been the outcome to your exam.
But scoring 70% and higher in the exam simulators can be an indicator that you have statistically much more chance to succeed than when scoring 61 to 65%, but it is not a general rule.
Many other factors may influence your actual result at the exam.
That being said, the best to do is to get enough self-confidence for the exam, and for that, a good preparation, reflected by good scores on the exam simulators is always a good option.
