AP Computer Science A — 2D Array

2D Array is the eighth of 10 units in the College Board's current AP Computer Science ACourse & Exam Description. It builds on ArrayList and sets up Inheritance.

Our 2D Array 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.
