Hello friend,

During the time of correction you can correct the details like 12 th marks , photo, and other details but don't miss the dates because after that you won't correct that.

Yes Chandrasekhar... You can correct your particulars. Correction will be started from 15th March, 2018. You will be allowed once to correct the details. So do it carefully.

All the best !

Dear Chandrasekhar 

Yes you will be able to correct academic details like Class 12 marks, etc. when the correction window is opened by CBSE from March 12 to 16, 2018. Some of the fields which will not be open to correction includes choice of exam cities, medium of language of the question paper, etc. 

Hope it answers you. All the best for exam!
