How to use this guide
The 2025–26 AP Computer Science A course is four units, 53 lessons. Self-studying, the steady pace is about 2 lessons per week, which carries you through all the content by early spring and leaves several weeks for full practice exams (multiple-choice and free-response) before the May AP CSA exam.
Two tracks below: a Full-Year plan if you start in August, and a Accelerated plan if you're starting around January and racing the exam. Pick the one that matches your start date.
The rhythm inside each unit: work through the lessons a couple at a time (read the lesson, then do the practice and the Question of the Day), and when the unit is done, spend a few days with its study guide to consolidate before the unit exam. The study guide is the review step, not a replacement for the lessons.
Accelerated January start · ~18 weeks to May
Starting late? You can still be ready — it just means a heavier weekly load and leaning on the study guides and practice exams. Expect 6–8 hours per week and about 4 lessons per week.

Cram-smart tip: take a diagnostic first, then protect the two heaviest-weighted areas of the AP CSA exam — Unit 4 (Data Collections: arrays, ArrayList, 2D arrays) and Unit 2 (Selection & Iteration) — plus the free-response (FRQ) practice.
Pacing questions
How long does it take to self-study AP CSA?
On the full-year track, about 2 lessons per week across the four units finishes with several weeks to spare for practice exams before the May AP CSA exam. Starting in January, plan on roughly 4 lessons per week.
What order should I do the units in?
Follow the CED order: Unit 1 Using Objects & Methods, Unit 2 Selection & Iteration, Unit 3 Class Creation, Unit 4 Data Collections. Each unit builds on the last.
When do I use the unit study guide?
After finishing all the lessons in a unit, spend a few days with that unit's study guide to consolidate, then take the unit exam.
