Following is the matter pls suggest me how to write...
The student has to update his /her postal address from time to time by sending the Hard copy address change application form on the SCDL address in order to avoid delay in receiving the Self Learning Material (study material) or any other hard copy correspondence dispatched by SCDL.
Henceforth the 'Edit profile link ' inside the Student Centre log in id on the SCDL website will not be active for address update/Change
