On my selection email, it said to expect a letter which must be kept via conventional mail within 1-2 weeks. I haven't received anything yet, (it's been almost 4 weeks) should I be worried? I formally accepted the scholarship online, and received notice from DoDMERB that I am medically qualified. Is there anything else I need to do? Sorry if I am making something out of nothing, I just want to make sure I don't miss anything.
