Hello aspirant 

As you have not mentioned the name of exam you are asking for so I am unable to help you precisely. But I think you are asking for NEET counseling so would like to tell you that it has started from 25 June and for further information go thorough this link

Also, if you want detail of exam other than neet then please mention it by commenting on the comment section. 

Like to help you.
