Hello,

In the last round of JOSAA there is no option of  " Slide or Float". In last round the only option is to " Freeze". And If you don't select freeze then your allocated seat will be cancelled it will not be auto freeze.

As its the last round, then there is no option for you to have any upgrade. So your seat gets automatically freezed and if you wish you have to take admission to IIT Delhi or else you have to leave the counselling. If you no other choice like upgrade as you have in the before round.

IIT Delhi is one of the best IIT's so if you get a chance to get into IIT then don't worry about and get into it, you will get enough scope to discover new fields as well as allied fields in future.
