AP Computer Science Principles: Coverage Map & Learning Gaps
Original foundation lessons and 12-question representative sample of a planned 48-question MCQ practice across selected goals; not complete CED coverage.
A partial map, not a completion score.
Current five-big-idea CED framework and the official big-idea multiple-choice weightings guide selection. Local objectives are not the complete official essential-knowledge list.
Mapping describes the available practice, not your mastery or readiness for the exam. Reviewed 2026-11-05.

Not yet covered
Identify program purpose, function, inputs, and outputs in described program designs.
What still needs work
- Not included in this representative sample.
Convert between binary and decimal representations and explain how a fixed number of bits limits the values that can be represented.
3 linked question families · 3 variants. Variants are not separate syllabus objectives.
What still needs work
- Selected foundation tasks only; not every CED essential-knowledge statement covered.
- Big Idea 2 is 17%-22% of the official multiple-choice weighting (course page read 2026-11-05); hexadecimal conversion is outside the selected foundation task set.
Compare lossy and lossless compression and reason about the tradeoff between data size and information fidelity.
What still needs work
- Not included in this representative sample.
Extract information from datasets and recognize how filtering and biased data affect conclusions.

- Not included in this representative sample.
Trace variable assignment and evaluate expressions as written in the course pseudocode.

- Not included in this representative sample.
Evaluate conditional execution and Boolean expressions in the course pseudocode.

What still needs work
- Selected foundation tasks only; not every CED essential-knowledge statement covered.
- Named Boolean operators and exact conditional syntax are reference-sheet details not confirmed by S1 official-page notes; objective stays conceptual until S3 captures them.
Trace repetition constructs (loops) and predict the values accumulated after a run.
What still needs work
- Not included in this representative sample.
Traverse and update list values and reason about how list traversal behaves.
3 linked question families · 3 variants. Variants are not separate syllabus objectives.
What still needs work
- Selected foundation tasks only; not every CED essential-knowledge statement covered.
- The list indexing convention used by the exam's pseudocode was not verified from official pages in S1; S3 must capture the reference sheet before content asserts it.
Trace procedures with parameters and return values, and identify where abstraction hides implementation detail.

- Not included in this representative sample.
Explain what simulations model and how randomness limits the conclusions a simulation can support.

- Not included in this representative sample.
Explain how packets, routing, protocols, and redundancy carry data across networks.

What still needs work
- Selected foundation tasks only; not every CED essential-knowledge statement covered.
- Big Idea 4 is 11%-15% of the official multiple-choice weighting (course page read 2026-11-05).
- Third-party unit numbering for this topic is observed to differ (code.org numbering in SERPs, 2026-11-05); all content must state its Big Idea mapping explicitly.
Reason about fault tolerance, redundancy, and scalability when systems fail partially.

Use the map with care.
- Original foundation lessons and 12-question representative sample of a planned 48-question MCQ practice across selected goals; not complete CED coverage.
- No full-length AP mock, automated Create-performance-task scoring, calibrated difficulty or official score prediction.
- Practice items are original text scenarios; no official exam items, figures or reference-sheet pages are reproduced, and the reading-passage and multiple-select formats are not simulated.
