can i make modifications in the web options of jee mains after the first round seat allotment??

Dear student,

In josaa counselling you have to fill your choices in your preference order and lock them. Before locking of choices there is a mock seat allotment round. This mock seat allotment round is held so that the students get to know that which college or seat they might get in josaa main round counselling on the basis of their preference order of preference order of filled choices. As per the results of mock seat allotment is students can change or reconstruct their order of colleges. But after locking the choices it cannot be modified that means if you have locked your choices and you want to again reorder your preference of colleges, then you cannot do it. Even after the josaa main round counselling or josaa Round 1 counselling, you cannot change your previously filled order of colleges.
