Hello,

According to the eligibility criteria of KVPY SA, students who have enrolled in class 11 with science stream during a particular academic year and have secured a minimum of 75% (65% for SC/ST/PWD) marks in aggregate in math and science subjects in the class 10 Board examination immediately in the preceding academic year are eligible to appear for the test. So, since you are repeating class 11 so you won't be able to sit in KVPY SA.

Hope it helps!

Good luck!
