after choice filling on 2nd November after 3 p.m. we have to lock our choices or it will get automatically locked
Dear Ankitanayancool,
After 3pm, if you have filled the details, them it will automatically get locked. But it is always recommended to do it by yourself, for precaution. You have enough time given, so you can fill in the details and lock it by yourself.
All the best, Cheers!!!
