Can I participate right from first the round in TNEA counselling or will I be allowed only in the successive rounds based on my rank?

Hello student ,
Based on your scores and cut off's in the hsc examination,  a random number will be alloted to you. Using this number, you will be called for the TNEA counseling. You will be informed prior about the date, time and venue of the counseling process. Thus you cannot participate right from the first round itself. Only when your turn comes, you will be allowed. You can go through the following link to know about the cut off's and ranks for the previous years and calculate your chances of selection in TNEA
