Hey Shruti ,

As per your mentioned query , you cannot take admission in ISI Kolkata in BSDS through Institute Admission Test (IAT). To get admission for BSDS in ISI Kolkata you have to give entrance exams like CUET UG and NEET .

Whereas , IAT exam is conducted by ISI Kolkata for admission in postgraduate courses and Bsc Hons .

I hope this helps you!

Revert for further query!
