JEE Mains paper 2 Scores

You have to wait for the JEE results, which will be released on the month of April by national testing agency NTA officially. The cut-off will be announced in April for JEE advance, so you have to wait till April to know the cutoff for JEE Advance, because it will depend upon the number of students appearing in April too. According to the previous year cutoff's your percentile might be less. I would like to suggest you to give second attempt so that you can improve your score. Use this formula to predict the rank by your percentile. Rank Formula = (100 - your total score) X 145386 /100.
1,45,386 is the number of students who appeared for the examination.
