In 2009 the University of Wisconsin-Extension's Academic Advanced Distributed Learning Co-Laboratory (AADLC) signed a partnership agreement with the Florida Virtual School (FLVS) to create an iPhone iOS application 1. The app, Revu4u (Review for You), is designed to help students prepare for Advanced Placement (AP) tests, which enable high-school students to acquire college credit in various subjects. Revu4u is a free app that allows students to download question "packs" covering different AP content areas.
