55 marks is how much percentile
Hello dear student,
Percentile can be defined as number of students scored below you or in other terms you can understand this that your score is better than number of students is your percentile.
So, percentile is not on the basis of marks . It can be calculated by:
Percentile = ( number of people whose score is less than yours/ total number of people) * 100
I hope this will help you.
