USC Education Benefit for Child?

<p>Although I’m not applying to USC this year ( will next year), when do you complete the Education benefit to get free tuition?</p>

<p>My dad worked for USC for 15 year and that enables me to get free tuition if I get accepted.
When should i complete the application for the Tuition Assistance for it?
Before I apply, or do i fill it out if i get accepted?</p>
