Advanced Placement Computer Science A (also called AP Java) is an AP Computer Science course and examination offered by the College Board to high school students as an opportunity to earn college credit for a college-level computer science course. AP Computer Science A is meant to be the equivalent of a first-semester course in computer science. The AP exam currently tests students on their knowledge of Java. AP Computer Science AB, which was equivalent to a full year, was discontinued following the May 2009 exam administration.
