Hi Viji.

For admission to B.sc at IISC,

1.a candidate needs to have passed 10+2 from a recognised board of Education.

2.the candidate must also possess valid KVPY/JEE/NEET UG score.

Unfortunately the last date of submission of application was on April 30,2019. You should have checked this much earlier.

For further queries feel free to ask.

Good luck!
