The MyChances API allows sites to provide college admissions predictions. Send (a) the college you want to know about, and (b) information about the student (SAT, GPA, etc). Receive a response giving a 0-100% probability, as well as meta-data about the accuracy, etc.
It's college application time again and high school seniors are starting to wonder where they'll be admitted in the spring. There's an API that can help them, or their parents (depending who's a better coder), get more insight into their chances.
