How can I manage to pay the fees at BITS Pilani without burdening my parents?

BITS Provides two scholarships
1. Merit cum need ( based on CGPA, upto 80% can be waived)
if you don’t mess with acads you can easily get 60% fees concession
2. Merit scholarship
As you come to campus on the joining day itself you can see different banks with their respective stalls in front of the academic buildings. All you need is your BITS ID card as security and loan repayment time is long enough (minimum 4-6 years).
I would say from my knowledge as a final year student , a average Bitsian once passed out from the campus can completely repay his loan from savings of his 2 years earnings.
My suggestion in the end is out of all the reasons one could think of not joining BITS Pilani, getting a loan should be the last reason and should not be much of a matter of concern.
The scholarships only cover the college fees. the mess fees doesn’t come under it
