Hello aspirant,

Hope you are doing great. You haven't mentioned about your category, I'm assuming it in general.  So, based upon the previous cutoffs for NITs and IITS, it is better for you to score 89 to 99 percentile. As the number of students attempting the exam are increasing day by day. It is better for you to score more percentile, than this.

You can check this link for any information regarding the cutoffs: https://engineering.careers360.com/articles/jee-main-marks-vs-percentile

Hope this helps you,

Thank you.
