Qadie, the last date to fill in the application forms has been closed as on January 20th, 2020. Now there is also no correction window for the application form. Right now, the only option you might have is to write to them at their email id: casbiaf@cdac.in (mailto:casbiaf@cdac.in) . We are not sure whether this would work or not, but this is the only way out at this point in time.
