If you need a minimum fee for the college you want to study in then I suggest you take a year off and repeat the process so that when if you get a better rank next time you write and perform then you get your desired college and the fee up to a minimum. But then if you want to move further having a 6460 rank in neet then you wouldn't get a good government college where the fees is less but would get a private one where you need to pay a lot of amount just to buy a seat.
