Hello,

The IISER Aptitude Test contains 25% Maths questions.

Although it is not mandatory to have Maths background in class 12, it is NOT possible to give the exam without Maths.

If you don't have Maths in class 12, then you can learn the basics to score atleast few marks in the exam.

You can learn more about the IISER test and all related stuff from this link:

Hope this helps.

Thanks.
