Every thing is easy for OBCs . Why are you taking tension???

Hello student,

There is an eligible criteria to qualify IAT and get admission in IISER. It is as, you must have rank with in 10,000 in common rank list if you are of general category. But if you are of any of reserved category(OBC that you have mentioned) then you must have rank within 1000 in reserved category list. Also, you must have at least 55% in 10+2 or equivalent exam. 

 I hope this will help you
