If I don't join the seat of R1

If I don’t join the seat of R1, will I be able to give fresh choices in R2? Do I have to give money again for R2?

Yes …you can fill up your fresh choices and no need to register again. Just log in with your previous details and fill your choices.

This is for All India counselling

Same for DNB?
