Hi aspirant,
For securing a management quota seat, the candidate has to pay a fee other than the course fee. This fee is known as donation fee. The donation fee is the additional fee that a candidate has to pay for direct admission. This means such candidates have to pay a donation fee plus college fee. This fess varies from college to college and you are required to contact college for assuring the extra fee amount.
Mostly the extra fee to be paid is double the original amount you normally have to pay.
Hope this helps.
