I completed my first step of registration on 7 march and i've filled exam city choice today. Will i get my my first preferred exam centre?
It depends on the exam centre you have chosen. Like if it’s a popular choice like a tier 1 city then chances are you might not get. The peripheral less populous centres are the last to be filled. As you have Taken a lot of time, their are chances of you getting 2nd or 3rd choice. You shall be lucky if you get your 1st choice.
