Now It is not possible to change in date of birth after registration in 10th board but in some cases it might change in case of genuine clerical errors like in cbse board changes DOB within the year of the declaration of result and no request is taken after the year.your school can help you in this but its a long and tedious process its better to go with the dob whichever written on your board if there is no issue but if you still want to change apply for it in cbse regional offices you may change dob but only after their approval.

Hello,

Hope you are doing well!

No its not possible. You have to study all the subjects again if you want to do 12th from maths again. You have to study physics and chemistry along with maths.

hope you are doing well

it's nearly impossible ro complete 12th again by just choosing only math subject.

you have to complete your 12th with physics, chemistry,math and English with an another additional subject like computer science or information technology (IT).

but you can apply only for mathematics examination of 12th from NIOS through on demand examination policy. It will be better to contact NIOS offices to the on demand examination policy.but keep in mind that you can not chose stream in 12th class while repeating. What subjects you had, you will have to chose the same one. You can not ask for science subject. If you really want B.Sc then again study class 10th & then opt for science subject in 11th & 12th.

hope this is helpful for you

all the very best to your upcoming future

Hi there. In response to your query the Candidate should note that double registration could actually lead to termination of candidature from the examination. In your situation even if you do not plan to sit for the examination the results for all examinations are declared separately, hence you can appear for single shift of that examination and not appear for the others.

Hope this answer helps; best wishes
