Naveen there are as such no fixed scholarships when you will be taking admission in most of the b-schools for all the category students. Very few of them have a scholarship policy based on your overall performance or merit rank. Mostly fee is same for all students irrespective of caste category or gender. Only a few government colleges like IITs offer concessions in the fees for category students. But once when you will join you will be introduced to the various scholarship from different organizations and governments.

There are many scholarships given by the regional government, organizations like Aditya Birla Group and also the central government. Most of these scholarships are based on the parental income (<4.5 lakhs), caste (SC/ST) and also the academic performance of the student. But even scholarships are available which are only based on your overall profile irrespective of family income or caste.

But you don't need to worry about any scholarship right now, you will be introduced to all the type of scholarships during your session. If you want to know about any specific college then mention the name, I will be able to tell you in a little detail.

Feel free to ask if you have any more queries. All the best!!

Most IIMs do have a number of scholarships sponsorsed by different companies based on merit. You need to visit their individual websites to get more details.
