Fin Aid question for admission daniel

<p>Hi,
I just got my financial aid letter yesterday, and the awards in the letter are not finalized yet since I submit the IDOC late. I'm just wonder if I should sign the letter or accept the awards online now? Or should I wait till my awards are finalized? I remember vaguely seeing something about we should sign every letter we get as confirmation of getting the letter, but I can't remember where i found that information... :D</p>
