Hello Balaji,

Thanks for contacting Careers360.

A general candidate needs to score 75% marks or be in top 20 percentile of a particular board. Top 20 percentile means you have to score more than 80% students of your board.

However ,board exam results no more decide merit list for addmission to IITs and NITs. Above criteria needs to be satisfied for admission but they won't be affecting anyones’s rank.

For OBC-NCL same criteria is there ,for SC/ST one needs to score 65% marks for qualifying.

Hope it helps.

Good luck!!
