Dear Madhavi, IISC, Bangalore offers admissions in its Undergraduate programmes through JEE Mains, JEE Advanced and KVPY. The Academic criteria says that you should have your 10+2 or its equivalent in 2018. Candidates currently in their 10+2 and likely to pass in 2019 are also eligible to apply. So unfortunately, you are not eligible unless you have appeared in KVPY-SA in 2017 and qualified for the fellowship.
