In India, the minimum eligibility requirement for most scholarships has been relaxed and there is no longer a mandatory 75% requirement in class 12 for appearing in JEE (as of June 2024).

Many state governments offer scholarships to students who score exceptionally well in class 12 (percentage might vary by state). Research scholarship programs offered by your state government's education department.

Some private engineering colleges or institutes might offer merit-based scholarships to students with high scores in class 12.

Several colleges or institutes conduct their own entrance exams for engineering admissions. These exams might offer scholarships to students who perform well.

Some colleges or institutes might offer scholarships based on your performance in their entrance exam or your first-year engineering results after joining as a dropper.
