Hi,

If you are applying through SCB (State and Central Boards) channel, you will have to appear in the IISER Aptitude Test (IAT). IISERs do not release cutoffs, you just get to know whether you are selected or not. But according to estimates, for general category students, a score of 110/180 is good enough to get in IISER Pune and Kolkata. To get into other IISERs like Berhampur, Bhopal, Mohali, Thiruvananthapuram and Tirupati, a student has to score atleast 70/180.

You will also have to pass 10+2 exam with science stream in 2018/19 and clear the board cutoff. Check your board cutoff at the official site: https://www.iiseradmission.in/eligibility/#E480.

Hope this helps.

Cheers!
