Hello aspirant,

Hope you are doing well,

The percentile is a statistical interpretation of data in which it changes every year. As it depends on candidates participated in exam at the particular year. For same marks the percentile will be changing every year. So it is not possible to calculate the CET marks without the proper data.

For percentile calculation the following fomulae is used:

{(No. of students having marks less than 57) / (Total number of students that appeared in the examination)} * 100

So as you see that you have to know the data of how many students that has scored below 57 and then the total number of student that appeared for the examination. If you know this values you can calculate it. Without that information it will be difficult to predict percentile.

Good luck
