Hello Aspirant

If you are planning to give IPMAT you should follow some basic criteria and they are as follows

1. Qualifying exam
2. Age
3. Minimum percentage of marks required

So ,While filling the application there is no such criteria that only students with Maths can apply for IPMAT.

For general category you will require minimum of 60% in 12th  and 55% in case of sc/st/pwd.

So you can select any subject and you will still be eligible.
