Hello,

As per the previous year mark vs percentile chart, your percentile will be  above 95%. It may change this year as per your performance in the exam.

Percentile says how you performed outof all the candidates and how much percentage of candidates are ahead of you and how much of them are behind you and it is calculated from the total candidates appeared in the exam.
