An update to those still concerned: (thanks for the PMs)
I am currently working with the administration, and I submitted the following plan for them to forgive me 100% of tuition in return for:
Administrative (ie paperwork) help during Spring Break and every Weekend.
Maintaining a 3.5 GPA and a 36 on the IB Exams.
So far, they seem to be quite pleased with the offer, but I have a few holdouts who will need to be swayed. It's promising to be a short but hard fought campaign, as the final decision must be made by March 1st (final due date for some IB thing or another).
Wish me luck guys!
