In 12th class my subject is maths not bio ... then Is I am capable to  apply for SCB?? 

Hi Sagar ,
Greetings !

No marks are released for the IISER aptitude test . Hence , cutoffs are not released.
You only get to know  whether you are selected or not .

But according to other candidates personal experience and the generalized question paper -
for general category student marks of about 110/180 will get him/her high chances of getting admission in IISER pune.

Hope this will help . Good Luck !
For any more query you can reply to this comment - I will be happy to help you :)
