Online Economics course for credit

<p>DD (international) is unable to take the AP economics exam this year as a Junior, but still wants to study advanced economics.
Options:
- An online course with Keystone and AP exam at the end of 12th grade. She has a reasonably heavy course load next year, so I don't think it's feasible.
- A university self paced course where she can get credit, something she could start right away. I found a couple with Univ. Missouri and Michigan State (this may not be available to HS students). Any recommendations?</p>

<p>Any suggestions would be helpful.</p>
