If you have not received an email from them saying this, then they have not processed it yet:
"Dear cawolf,
We have successfully received and processed STATE UNIVERSITY transcript on your behalf.
To view the status of all your transcripts, please login to your AACOMAS application and click on Manage My Programs, then Program Status. Hover your mouse over the information icon for additional information.
Sincerely,
AACOMAS Customer Service"
Currently it seems like they are processing transcripts that were received at the beginning of this week.
If you have submitted, you can check by following the instructions in the above email.
There is no way of checking if they have it, but have not processed it, unless you FedEx'd it with a tracking number.
