Let's say 31st August 5.00 pm is the last day for filling your choices and locking them to save your options. But for some reason, though you filled in the Colleges, you forgot to lock or save your choices. WBJEE Council will not go and manually lock your choices. The system will automatically lock your choices after 5pm on 31st August. It is a pre designed option like your Phone lock. If you have pre set your mobile lock for 30 seconds, you do not have to go and lock your mobile every 20 seconds. You leave it unattended, the mobile pre set settings will lock the phone after 30 seconds on its own. Its the same concept.
