Hello Antony,

Percentile is calculated to compare marks among candidates. To be more specific percentile is number below which a certain percentage of scores or observations fail. Now if we talk about will the percentile change or not, then my answer would be if evreyone gets bonus then percentile will not change but if bonus marks are given to only some number of students then obviously percentile is going to change. So, do not worry about it. I hope I answered your question.

Thank you !!
