Hey,

AFMC usually require from students who have more that two year of gap after completing their class 12 th to submit a gap certificate at the time of admission.

It is mandatory for everyone who falls under this category. But if you don't have that certificate I will suggest you to inform the authorities in advance regarding you problem. They will surely lend you some time so that you can prepare your gap certificate and submit it to them.

Hope that solves your concern.

Thank you.
