Dear Aspirant,

Before the WBJEE counselling starts, they provide a specific date for "Choice Locking" which, if I am correct, was on the 25th August'20. After the results of the 1st round of WBJEE or even after commencement of the same, you ARE NOT allowed to change your choices.

Your college and stream choices are final and the order in which you placed the colleges will directly affect the colleges that you get in the subsequent rounds of counselling.

Hope this helps.
