It can take up to a month to be notified if you are awarded a scholarship by one of the boards. If you hear nothing, that means you've been reboarded for the next and any subsequent boards. They do not notify you if you have been reboarded (generally... my DS was informed he had been reboarded for the Marine option). You may not hear an official negative result until early to mid-April. Be working those backup plans, which of course can include NROTC as a college programmer. This is the course my DS took and he received an in-college scholarship in his sophomore year, which BTW are just as competitive, but the participants are different.
