IIM Ahmedabad students can benefit from various scholarships and financial aids for their PGP/PGP-FABM.
Some of these scholarships/ financial aids are- Aditya Birla Group Scholarships, Dunia Scholarships for scholastic excellence, OP Jindal Engineering and Management Scholarship, T.Thomas Scholarship, PGP Alumni Endowment Funds, IIMA Special Need Based Scholarships, etc.
It is possible to accept scholarships/ financial aids from more than one source to cover your yearly study and lodging expenses entirely. However, your selection for these financial benefits depends on the selection committees of the respective sources offering these scholarships/monetary aids.
You can check the IIMA official website to gather more information on the subject.
Rather than opting for scholarships, I would suggest financially weak students apply for Fee-Waiver seats. The entire fee is waived. Another option can be student loans. The job you will get post-MBA from IIM Ahmedabad will get you enough savings to pay your loan. Also, the loans carry very low-interest rates.
The last option should be scholarships. These scholarships are given based on merit only. The financial background of the candidate does not matter. The ABG or Aditya Birla Group Scholarship falls under this category and is the most desired scholarship in the whole country. The scholarship package is INR 3 lakh per annum for the IIMs.
