Hi, 

The neet counselling registration portal opened after 7pm on 19th june. Last day of registration is 24th june by 5pm.

Choice filling starts from 20th june and the last date of choice filling is 25th june by 5pm.

I suggest you be very careful while filling choices and pay importance to filling colleges in the order of your chances of getting a seat with the college where you have maximum chance being on top followed by the colleges where chances are less.

All the best
