If you are from CBSE board then CBSE gives scholarship to needy and meritorious students having decent percentage in 12th board. The scholarship has many other criteria too, so just Google this and get complete information.

And if you are SC/ST student than Central government also provides you with some kind of scholarship, its details are released in newspaper from time to time.

And also check, that if your institute NID provide some scholarship program.

I hope my answer helps. All the very best for your future endeavors!
