I have scored 99.6 percentile in JEE mains this year. But dueto some technical glitch my choice filling has not been uploaded. Mentally , physically my self and my family is in state of shock. Please help me if there is any possibility. Many has advised for spot selection. Please provide details .

Dear student,

It's very unfortunate that even with this much good percentile score you will not get any good NIT college this year from josaa counselling. As you have secured 99.6 percentile score, then it is a very good score and with this much score you had the chance to get many good colleges, but now as the dates of choice filling of josaa are over and you don't filled any choices ( due to technical problems ), then there is no chance that you can fill choice between any round. So it's better that you opt for CSAB counselling which is also known as spot round or jee mains special round counselling.

Csab - Central seat allocation board, is responsible for filling the vacant seat in NITs, IIITs and Gftis.
The csab counselling is held if the seats remain vacant after the completion of josaa all round counselling. The Official dates of registration of csab has not come yet.
Also for participating in this csab counselling, you must have to pay the participation fees of around rupees 36500 and if you get a seat in Csab counselling and if you accept it then again you will have to pay the seat acceptance fee of rupees 35000. Now as per your rank you can get any nits of your preferred branch in Csab counselling ( if seat remains vacant after josaa all round counseling). So you have to wait for csab counseling and you can get many good nits with this much score.
