Will I be able to take UPSC after first 3 years of the IIM Indore’s IPM course?

Yes, after finishing the first three years of the Integrated Programme in Management (IPM) program at IIM Indore, you will be eligible to sit for UPSC. 

After completing 3 years in the IPM course, you will be given a UG degree in Management Studies (BMS). 

After earning your BMS degree, you have the option of pursuing a management career or studying for the UPSC to enter public service. IPM program offers a strong foundation in general studies that might be helpful for studying for the UPSC, even though it is primarily focused on those who wish to pursue a career in management.

It's important to note that the UPSC is quite difficult and competitive and that it requires extensive study and effort. If you're thinking of appearing at UPSC, you should start studying as soon as possible and stick to a strict study schedule.
