Is it better to go for DU BMS instead of IPM of IIM Indore

Since you’ve not given any context to the question, the answer in any normal circumstance would be yes. Let’s understand why spending more than 5 lacs on an IPM degree is not worth your time and effort. 

• Fee: BMS DU charges around 50,000 for the entire course where IPM fee is unnecessarily high just because of the IIM tag. I am not saying that there will not be any difference between the curriculum but the difference is not worth the money you’re paying. 
• Syllabus: Although IIMs are known for their pedagogy and surely you’ll get professors who will change the way you see a subject. This kind of exposure at such an early stage of your life will widen the possibilities but if we talk about the syllabus of a BBA degree and that of a BMS degree, the difference is pretty evident. 

BMS is a slightly analytical degree that would give you an edge over students pursuing BBA or BCOM. I have seen BMS students acing CAT after basic preparation cause of their good grasp on logical reasoning. It’s a given fact that an average BMS students is more likely to score well in CAT than an average BBA/BCOM student.
