Frequently Asked Questions
How does daily practice work?
Each day, we release new practice questions for all 4 AP CSA units. Questions progress through each unit's topics following the official College Board curriculum. Simply pick your unit(s) and practice for 5-10 minutes daily.
Are these questions like the real AP exam?
Yes! All questions are designed to match AP exam style and difficulty. You'll practice code tracing, algorithm analysis, and conceptual understanding—the same skills tested on the actual exam.
Which unit should I start with?
It depends on where you are in your course! Units 1-2 cover foundations (variables, control flow). Units 3-4 cover object-oriented programming and data structures. If you're mid-year, Unit 3 might be perfect. Starting out? Begin with Unit 1.
How many questions are available?
We release 4 new questions daily (one per unit), which means 28 questions per week. Questions rotate through each unit's topics on a 7-day cycle, so you'll see fresh content every week.
