Hello.

Well marks doesn't matter if there's percentile system. Your marks and would depend upon the what is the highest makes obtained, what is the marks obtained by those who have higher percentile than you and how many students appeared for the exam. NTA has a method to calculate rank according to your percentile.

However 61.8 is certainly less and you need to work harder this time to get into some good college.

Best of luck!
