Dear Meenakshi,

First and foremost, let me state that IISc Bangalore is a fine choice of institution, especially if you have a disposition towards a career in scientific research (which is very much in demand).

Coming to eligibility, with 60% in 10+2 and PCM as your subjects, you can opt for the bachelors degree in IISc. Further to that, NEET UG marks and rank will be used for selecting among aspirants for the admission. There is no minimum marks stated by the IISc Bangalore in NEET. I believe the admissions will be done on the basis of merit (based on your marks and rank in NEET as compared to other candidates).

Aside from appearing in NEET 2019, you will also have to fill the online applications for IIScB. The applications will begin from February 2019 onwards. They are likely to remain open till April end of 2019. The application fee would range like this- Rs. 500/- for GN/OBC/KM candidates and Rs. 250/- for SC/ST/PWD categories.

Hope it helps.

All the best!
