Hi

No, there's no way to remove your biology from your certificate/marksheet.

This is because,

If you have 6 subjects ( 5+1 i. e 5 main and 1 optional or additional ) then irrespective of the optional/subjected opted by you, if you fail in one subject then it takes the place of optional or additional subject and the optional subject you had chosen becomes your main subject and the same is reflected on your marksheet and your result status is pass.

One can choose either to appear in the compartment examination of failed subject or not to appear as he has  already passed 12th.

Even if you had appeared in compartment examination of biology as a private candidate, still they would just provide you a  private passing certificate of biology only . Your original marksheet remains the same with failed in biology. So, there's no way to remove it .

But don't worry you won't face any problem

††††Personal experience :- I had friend who failed in maths and it was replaced by his optional hindustani music and his result status was pass,  but he  didn't face any problem and is studying BA in Allahabad university.

So, no worries even if failed biology is there in the certificate ,  what all matters is that you are pass in 12th.

Thank you
