changing D.O.B in cbse tenth std certificate

Sir, my date of birth on the cbse tenth std certificate is wrongly printed as 28/05/1994 But my actual dob is 05/07/1993 Now when I was planning to get the passport, I learned that dob in the birth certificate and school certificates need to match. From the websites of cbse, I got to know that cbse doesn't permit corrections in dob in the certificates two years after the issue of the certificate. I am now in the last semester of engineering. I was planning to work abroad. Is there any way I could get the dob on both birth certificate and cbse certificates same so that I could apply for the passport. Thanx in advance.
