Vin,



There's no way to know the marks from percentile

Though you can calculate your rank from your percentile by using the formula



((100-percentile)*no of candidates who gave the exam) /100.



This is the formula you can use.



And there's no such way to calculate marks from percentile. You can just have a average figure like if some percentile is 98.6 his marks will be like 170-180.
