Hey aspirant,

It is difficult to understand which particular entrance examination you want to know about.

Nevertheless, the basic procedure for participating in counselling rounds of any entrance examination is :-

1) Registration

2) document uploading

3) registration fee payment

4) choice filling

5) finally participating in counselling

In most cases, it is not possible to sit for counselling if registration is not done. Registration is the first abd foremost step and the candidates must not miss it. You can contact in the helpline numbers of the particular entrance administration office and can ensure about this rule.

Hope this helps,

All the best!
