A percentile is a comparative or relative score between a particular score and the scores of the rest of the students. It depends on various dynamic factors such as:

• Total number of students appeared
• Number of students qualified
• Performance of all the students in each session

If you want to know your rank from percentile, then you have to mention the particular exam in which you appeared.

Simply you can understand this as : Getting 96 percentile means you are ahead of 96% of the students appeared for examination.
