Dear Ismat

You can still do the choice filling and locking before 5:00 PM today. Note that you can give as many choices as you wish, but remember to keep your choices in the order of your preference.

As for second round of counselling, all the candidates, irrespective of whether or not they fill the choices in round 1, will be needed to submit fresh choices during the windows which will open right before second and mop up rounds. 

Besides that, if you have registered and do not fill the choices, you will remain eligible for the second round, but will not be considered for allotment of seat in first round. 

I suggest you to go ahead and make your choices and enhance & secure your chances of getting a seat. 

Hope it clear your doubts.

All the best!
