AP CS Principles Study Plan: Timing & Strategy

Eight weeks of AP Computer Science Principles, one week at a time

Each week names the AP Computer Science Principles units you work on and one thing you finish and keep. Tick a week off when the deliverable exists, not when the time is up.

Eight-week AP Computer Science Principles schedule
Week	Focus	AP Computer Science Principles units	What you finish that week	Done
Week 1	Diagnose and start the Create task	Creative Development	An error log plus a chosen Create-task idea with a list and a procedure already sketched.	Week 1 complete
Week 2	Build the Create-task program	Creative Development; Algorithms and Programming	A working program with one student-developed procedure that takes a real parameter.	Week 2 complete
Week 3	Finish and document the Create task	Creative Development	The video, the written responses, and the code segments selected and captured.	Week 3 complete
Week 4	Data	Data	Convert twenty numbers between binary and decimal by hand, and explain lossy versus lossless compression with an example.	Week 4 complete
Week 5	Algorithms	Algorithms and Programming	Trace ten pseudocode segments in a variable table, including nested loops and a binary search.	Week 5 complete
Week 6	Programming concepts	Algorithms and Programming	Write ten short pseudocode procedures in the exam's reference language, not in your usual language.	Week 6 complete
Week 7	Systems, networks, and impact	Computer Systems and Networks; Impact of Computing	A chart of protocols, fault tolerance, and one written tradeoff analysis for a real computing innovation.	Week 7 complete
Week 8	Full timed rehearsal	All five units	One complete timed 70-question section, scored by big idea.	Week 8 complete

AP Computer Science Principles exam strategy

A plan tells you what to study. This tells you how to spend the exam itself. Work these decisions into every timed week above, so exam day is a rehearsal rather than a first attempt.

AP Computer Science Principles timing: what one question is worth in minutes

Work out your pace before exam day so you never discover it during the exam.

Section timing for AP Computer Science Principles
Section	Time	Questions	Pacing note
End-of-course multiple choice	2 hours	70 questions	About 1.7 minutes each. Code-tracing items are slower, so bank time on the vocabulary and impact items.
Create Performance Task	Through-course	Program plus written responses	Done during the year, not on exam day. Start it early enough to record the video and write the responses without rushing.

Calculator and reference rules for AP Computer Science Principles

Calculator rules change from section to section, and they are different on every AP exam. Practice each section under its own rule.

What you may use in each part of the AP Computer Science Principles exam
Section or part	What you may use	What that means for your work
End-of-course multiple choice	No calculator	Binary, compression ratios, and speedup are all small mental arithmetic.
Provided during the exam	Exam Reference Sheet	The pseudocode language is given to you. It is not Python or JavaScript, and reading it as if it were is a common way to lose easy points.
Create Performance Task	Not applicable	Built during the course on a computer, submitted before exam day, and scored separately.

The full relationship-by-relationship review lives on the AP Computer Science Principles formula and reference section.

AP Computer Science Principles task verbs and what earns the point

Free-response points are written for a specific verb. Answer a different verb and the work can be correct and still score zero.

Task verbs used on AP Computer Science Principles free-response questions
If the prompt says	The point is earned by
Identify	Name the line, the variable, or the procedure. One phrase.
Describe	Say what it does from the outside - what goes in and what comes out.
Explain how	Walk through the logic step by step, referring to your own code by name.
Justify why	Say what problem this choice solved - why the list, why the procedure, why the parameter.
Trace the algorithm	Write a table of variable values after each pass. Guessing from the shape of the code is where most errors happen.

How students lose AP Computer Science Principles points

These are specific to this exam. Read them again the night before.

The Create task needs a student-developed procedure with a parameter that actually changes what the procedure does. A parameter that is never used, or a procedure that ignores it, fails that row of the rubric.
The task also needs a list (or other collection) used to manage complexity. Storing one value in a list does not count - the program has to be genuinely harder without it.
Written responses that describe what the program does instead of how it works. Reference your own code by line and name, and explain the logic.
Reading the exam pseudocode as your own language. Its list indexing and its loop syntax differ from Python and Java, and questions test exactly that difference.

AP Computer Science Principles priorities to protect every week

A useful plan is course-specific. Whatever else a week contains, keep time for the content and response habits that decide AP Computer Science Principles scores.

Create-task evidence capture
List and procedure requirements
Algorithm tracing
Internet protocols
Ethical impact tradeoffs

AP Computer Science Principles unit-by-unit response plan

Binary, compression, abstraction, data analysis

Practice recognizing how data can be tested, naming the evidence or method required, and writing a concise response that earns credit.

Required

Algorithms and Programming

Variables, lists, procedures, algorithms, simulation

Practice recognizing how algorithms and programming can be tested, naming the evidence or method required, and writing a concise response that earns credit.

Required

Computer Systems and Networks

Internet protocols, fault tolerance, parallel computing

Practice recognizing how computer systems and networks can be tested, naming the evidence or method required, and writing a concise response that earns credit.

Required

Impact of Computing

Bias, privacy, security, digital divide

Practice recognizing how impact of computing can be tested, naming the evidence or method required, and writing a concise response that earns credit.

Questions about AP Computer Science Principles eight-week study plan and exam strategy

How should I split eight weeks of AP Computer Science Principles revision?

Week 1 is “Diagnose and start the Create task” and you finish it with one thing you keep: An error log plus a chosen Create-task idea with a list and a procedure already sketched. Week 8 is “Full timed rehearsal”. Start at the week that matches the time you have left, not at week one.

How should I pace myself on the AP Computer Science Principles exam?

End-of-course multiple choice — About 1.7 minutes each. Code-tracing items are slower, so bank time on the vocabulary and impact items. Create Performance Task — Done during the year, not on exam day. Start it early enough to record the video and write the responses without rushing.

What does “Identify” mean on the AP Computer Science Principles exam?

Name the line, the variable, or the procedure. One phrase. Answering a different verb can be mathematically correct and still score zero.

What is the biggest scoring trap on the AP Computer Science Principles exam?

The task also needs a list (or other collection) used to manage complexity. Storing one value in a list does not count - the program has to be genuinely harder without it.
