Dear shrijit
You didn't mention your 12th board name and Cut-off list for scb channel 2021is not declared yet officially. Check for previous year cut-offs to get an idea of your eligibility. Some of them are listed here.
50% of the seats are reserved for candidates qualifying the IISER aptitude test. You have to only qualify the cut-off to apply, after that ranks will be declared on the basis of your IAT performance only.
