Deadline to Accept Financial Aid?

<p>Sorry, sorry, I found the answer.</p>

<p>"While there is no set deadline to accept your awards, your aid will not be available until you do so."</p>

<p>I have a question about the aid, I got offered 3 aid:
Federal Direct Subsidized Loan to meet need<br>
Federal Direct PLUS<br>
Federal Direct PLUS - Optional</p>

<p>can anyone tell me what's the different?</p>

<p>You should just call up the financial aid office and find's not worth getting a wrong answer about something that important here on the boards.</p>
