Hello Shanur,
The admission depends on which course you want to opt for. If you want to do Integrated PhD program, then you have to have a valid JAM score according to the requirements of IISC Bangalore. But, if you wish to join research or M,tech course, then you got to do MSc and then answer GATE in order to apply in IISC.
'For more information, you can visit the official website of IISC Bamgalore.
Good luck and stay safe!
