Hello Aspirant !. Don't worry .Even my friend has faced the similar situation, when he has to give study certificates in EAMCET counselling. Here is the solution for this.

First of all in any counselling of Competitive Examinations, when they ask for study certificates, it means you have to submit the bonafide certificate that is provided to you, when you leave the school. So, If you have Bonafide certificate on which the academic year in which you studied is mentioned. In that certificate if your class 6  to class 10 are mentioned, then you don't have to worry. You, can submit that in counselling and it gets approved.

Incase if in the Bonafide, class 6 in which you have studied is not mentioned. Then, follow these steps :

*Visit the school in which you have passed out.

*Explain your situation to the principal there.

*Request him asking the new bonafide in which the information regarding your class 6 is mentioned.

*The principal would say it to the non-teaching staff and they will write and give you the new bonafide.

The School management will surely give it. Then provide your Bonafide in the counselling. Don't mention to the Counselling officers that your Bonafide is a new one and what made you get that again.

All the very Best !!
