Hello aspirant

If you have lost your original class x mark sheet then you must apply for a new mark sheet from school where you have completed your class x.

Send an official application and request them to provide a new one.

You will have to provide the reason . It may take a few days but you will get a copy of your class x original mark sheet.

You may go personally to your school or write an email .
