Hey aspirant the answer you needed,

In JEE MAINS exam the college admit the candidate based on the percentile they scored ,the mark does not play role in admission to the enginnering colleges.

There is a great difference in mark and percentile ,suppose your score is 100 marks in JEE mains  out of 8 LAKH  candidates then if the topper score is 150 out of 300 then your percentile will be 96 -90 .

The  JEE mains exam the math marks obtained by the student is taken for the rank .In the whole a  minimum of 30 marks is needed to qualify jee mains, scoring marks in a particular subject does not mean that you are qualified or get a higher percentile.

Hope you are satisfied with the answer .
