how to calculate marks using percentile

Dear 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

You can convert a rank k into a percentile by: Computing 100k/N. This value will range from 100/N through 100N/N=100. Note the asymmetry: the highest is 100 but the lowest is nonzero.

So as you see that you have to know the data of how many students that has scored below your percentile or marks 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 or marks.

Hello

Calculation of marks using the percentile is tough. However, expected rank can be calculated using the formula mentioned below-

100 - your total percentile score is the percentage  of people ahead of you. 869010 are the number of candidates appeared for Jan exam.

So rank formula is (100 - your total score) X 869010 /100. If the number of candidates for April exam increased to 1200000 then your final rank shall be (100 - your total score) X 1200000/100

Good Luck!
