This site was developed to help students in AP Computer Science A practice their skills solving AP-style problems.

This site is maintained by Richard White, an AP Computer Science and AP Physics teacher working in southern California. I am happy to correspond with computer science students and teachers—particularly if you notice an error in a problem!—but am unable to offer tutoring or individual problem-solving advice. I am a full-time instructor, and working with my own students keeps me very busy.
