hello aspirant,

you should contact your school office for the correction in the 10th marksheet, while we finalise our details for the class 11th and class 12th exams, a list comes from the CBSE, giving a last chance to students to correct any sort of mistakes in previous detail fillings, you should wait for that form to come and make sure that you do not miss it, else you have to go to the CBSE office for the correction.

keep in touch with your school office regarding the details for the correction form, your problem will surely be solved.

hope that helps

all the best
