don't panic ,cgfns will again send the evaluation paper to ur college and ur college has to fill it again and send it back to the cgfns from where u had applied it..now this time u call ur college and ask them to send themself  via simple registraion mail and not to mentioned any personal name outside the envelope..(which DHL does,so don't ask them to send through dhl).i know in this case ur college is cooperative to u.
the most important thing is that the date that u have mentioned while applying for cgfns must be the same that ur college will send to the cgfns.so remember the date and ask ur college to put he same date in ur cgfns paper..otherwise they will resend it again.good luck
