JEE Advanced

No, once you have locked your choices you would not be able to change them. However, you have the option of freeze, float and slide once you get any seat in any round. (A) Freeze: Candidates accept the offered seat and indicate that they are content with the allocated academic programme and that they do not want to participate in further rounds of seat allocation. Such candidates will NOT be considered in subsequent rounds of admission. (B) Float: Candidates accept the offered seat and indicate that, if admission to an academic programme of better/higher preference in any Institute is offered, they will accept it. Else, they will continue with the currently accepted academic programme. Such candidates will be considered in
subsequent rounds of admission. (C) Slide: Candidates accept the offered seat and indicate that, if admission
to an academic programme of better / higher preference is offered within the same Institute, they will accept it. Such candidates will be considered in subsequent rounds of admission.
Best of luck.
