I have passed my 10th board from s k p vidya vihar, CBSE Affiliated (Bhagalpur- 812002, Bihar) in 2005.
Due to some miss happening I lost all my mask sheet and certificate.
During my course of examination in 2005, Bihar region was under Allahabad zone but now Bihar region has sifted to Patna zone.
Where should I submit the form for duplicate issue of certificate either Patna or Allahabad?
And whether can I submit the form through post?
Kindly help me with the said above problem.
