Hello aspirant, hope you're having a a great day.
So, the INSPIRE program is mainly for students who are really good in science, and it’s managed by the Department of Science and Technology (DST), Government of India. For Class 12 students, the award you're probably referring to is the INSPIRE Scholarship for Higher Education (SHE).
If you’re in the top 1% of your Class 12 board exams or if you have a really good rank in exams like JEE Advanced (top 10,000), or if you qualified NTSE, KVPY, or international science olympiads, then you might be eligible. But the scholarship is only for students who go into pure science fields after Class 12: like B.Sc. in Physics, Chemistry, Biology, or Maths. It doesn't apply to engineering or medical courses.
