Log into your program. locate your options menu. It should look like one of these. For some reasons my two courses look very different in their setup.
click on "Make a Payment" or "Billing & Payments"
There should be a section for Miscellaneous Payments, like so.
Click Study Time Extension and then Pay. If this option is not available to you, please contact the school for assistance. I hope this helps you,and good luck with your studies.
