Hello Aspirant, Candidates are permitted, if they so desire, to change or re-order their choices,

delete earlier choices and add new choices any number of times until they lock their

final choices before final locking date. After the choices are locked, candidates will not

be able to change their choices. Their Last Saved Choices will automatically be locked

after this deadline. Hope your query is answered, if you have any doubts please let me know in the comments below.
