Hello candidate,

There is no reason to worry if you do not get the option to lock your seat then most probably there is the final round of counselling process so even if you just select the say they have provided you with any of the options, this automatically gets locked as the last date with the council has to offer yourself at if you are interested from the seat provided to you have to just confirm your seat allotment once the counselling gets over.

Hope you found it helpful. If you have any further queries regarding any specific questions, feel free to post it here!!
