See if u are opting a college through COMEDK entrance exam u must be aware that the college tuition fees lies between 1,15,000 to 2,00,000. So if u want to take concessions in ur btech career u should have applied the scholarship forms for that.
Otherwise u can ask for any concession in the fee structure if u are having a good merit point in the entrance exam but that can be discussed only when u physically approach them.
Hope it helped u. Ask if any query.
