Name and date of birth correction in h sec certificate

Sir,

In my Higher secondary certificate my name has been wrongly printed as V.Jebaraj. But actually it is V.Jayaraj, My date of Birth is 4.3.1974. But it has been wrongly printed as 05.05.74. My school is situated in Tuticorin district. I have to change this immediately. But I am here in coimbatore. Please advise me how to change this ONLINE. 

Thanks & regards.
