Sir i have applied for ap pgcet 2018. i have entered my 10th hall ticket no. Instead of btech number.please help me sir.

Sanka as you have mentioned 10th hall no. then it is correct, you need to mention your college/university hall ticket number from where you gave your last exam of B.tech. Now as you have done the mistake so I recommend you to write a mail to the official email address from the website with all your personal details, application number and the correction you want to make. Also, make a call to the administrative department mentioning your problem. And ask them other than doing mail is there any other procedure you need to follow to correct your mistake.
