Hey

I would say a big yes.Taking Maths with Commerce in +2 is best course if you want to go for IIM Indore after 12th.Because in the syllabus of IPMAT more than half of  the topics in their syllabus is related to Maths and English and some of them are from the course which you studied in 10+2.So it would be very beneficial for you take Maths as your subject with commerce also it is best combination for students who want to pursue management course.

Hope It Helps

Best Of Luck!
