AP Computer Science Principles — Data

Data is the second of 5 units in the College Board's current AP Computer Science PrinciplesCourse & Exam Description. It builds on Creative Development and sets up Algorithms and Programming.

Our Data set has 12 practice questions, each with a written explanation, a one-line key takeaway, and a rationale for every wrong choice — so you learn why the right answer is right and why each distractor is tempting. You can work them as a timed set or read the worked solutions straight through.
