Hi aspirant,

Whenever the result allotment of any rounds are out, you will need to select one of the three options provided by  JossA to proceed. Note that students have the option of either accepting the allotted seats with not willing to participate in the next round or accept with willing to participate in the next round or reject the allotted seat with not willing to participate in the next round counselling.

In case you want to freeze your choice, you will have to download their seat allotment letter. Students have to log in using their application number and password for downloading their seat allotment letter. After downloading the allotment letter of JoSAA 2021 counselling, students have to pay Rs.35,000 as seat acceptance fees ( Rs15,000 for reserved category). JoSAA counselling Fee can be paid in online mode or through e-challan.

Hope it helps!!
