i want to correct father's name and surname in my 10 marksheet. then what step i can take

Hey!

For the purpose of making any corrections in the 10th marksheet be it correcting the names of your parents, do contact your school first. It can be that the school will get any information corrected themselves by engaging in the procedure with the boards office or it can be that you may be directed to the office yourself and you will have to provide necessary documents they ask for. You will have to write an application first. The procedure may slightly vary with different boards. It can be that the procedures may have a slight difference ascertaining to different boards like CBSE or other state boards. But first contact your school regarding it. You should also have identity proofs.

See the rules for the changing of the names on the marksheet is simple. The first thing is that you need to contact your school, most of the schools have there forms for such changes and that way on submission of the required documents you will get it done. If not, then you have to contact the Regional office of your 10th Board and get it discussed, they will directly give you the forms and on paying the required fee for the correction, you will get it.

This are the two ways you should go for and any of it will work and you will get your corrected marksheet in 2-3 months of time.

Have a great day!
