I applied for IPCC exam online and after taking the print-out of the application, i forgot to attach / Paste / Add my photo and sent the application to the concerned address. What to do now?
No problem with that. Its a common mistake done by the students. You take another print out of the application and attach the photo and complete the remaining formalities and add a letter stating that this is the second time you are sending the application, etc.
Even if you leave it without sending the application second time, there is no problem with that. You will receive the Admit card, but without the photo. After taking a print-out of the Admit card, then attach a photo on that and attest the photo with a CA.
