Ipcc exam form

Hello:-)I am giving my second of ipcc in November.As I couldn't apply for the exam online,I opted for manual submission this year.I had posted the letter on 25th of august assuming it would reach Delhi by 30th.but I got a message from the Indian postal service saying it is delivered on 5th I.e.today.Are there any chances of the Institute rejecting it ?or the date of application of the form is the deciding factor.please help.
