Hello Yateesh Vijaya Kumar,

For the eligibility to apply for KVPY you need to have at least 75% for general category and 65% for SC, ST or PWD in science and maths. So, check for your score in science and maths.

It goes the same for 12std too. The candidates should have at least 60% for general category and 50% for SC, ST or PWD in science and maths.

Hope this helps.
