How do the current exam format and the 2025-26 revision differ?

Current exam format · checked August 3, 2026

The current AP CSA exam runs in Bluebook and has 42 multiple-choice questions (90 minutes, 55%) and 4 FRQs (90 minutes, 45%). The 2025-26 revision removed Inheritance and Polymorphism from required content and added File I/O and Dataset Processing. That revision year is historical context; current preparation should follow the Course and Exam Description for the student's exam year.

Was AP CSA Inheritance dropped from the exam scope?

Correct. With the College Board's 2025-26 overhaul, Inheritance and Polymorphism were removed from the AP CSA required exam scope. The reason this change matters is clear.

  1. Existing textbooks (older editions of Barron's, Princeton Review) and many online lectures still treat inheritance and polymorphism as core topics.
  2. Materials from the 2024-25 school year or earlier may include units that no longer match the current required scope.
  3. Conversely, if you're not familiar with the new scope (File I/O and dataset processing) you'll run into unfamiliar problems on the actual exam.

Before instruction begins, CIT checks the Course and Exam Description for the student's exam year and identifies material in older resources that no longer matches the required scope.

How do I prepare for the digital AP CSA exam?

The current AP CSA exam is fully digital in the College Board Bluebook app. Students should use the official test preview to learn the Java-response input flow for their exam year.

  1. Adapting to the Bluebook app environment: Install the official College Board app and get comfortable with the flow of writing Java code on screen. It requires different muscle memory than writing by hand.
  2. Learning the new framework: Focus on File I/O, the Scanner class, file reading/writing, and dataset processing logic. This connects with advanced work on arrays and ArrayList.
  3. Repeating mock exams in a digital environment: You need to solve on a digital screen, not paper mocks, to adapt to the real thing. CIT's ExamPrep platform provides mock exams that reflect the digital exam environment.
  4. Training FRQ typing speed: Students who type more slowly than they write by hand or find entering Java syntax awkward need separate training.

Where do international-school students in Korea take the AP CSA exam?

Test locations and outside-student registration vary by school, center, and exam year. Ask the student's school AP coordinator first. If the school does not register the student, check Fulbright Korea and the College Board registration guidance for current availability, procedures, and deadlines. CIT is not a test center and cannot confirm a center's capacity.

AP CSA vs. AP CSP: What's the Difference?

AP CSA (Computer Science A) and AP CSP (Computer Science Principles) are both AP CS courses administered by the College Board, but they differ greatly in content and difficulty. It's important to choose the right course based on your child's current level and goals.

Distinction AP CSA AP CSP
Programming language Java No language restriction (mainly Python, JavaScript)
Exam format 42 multiple-choice (55%) + 4 FRQs (45%) Bluebook digital 70 multiple-choice questions (70%) + Create Task and 2 written responses (30%)
Difficulty High (college CS1 level) Medium (intro CS level)
Recommended for Students with prior programming experience or those aiming for a CS major CS beginners and students who want to learn a broad range of CS concepts
Selection factors School availability, current Java readiness, intended field, and workload School availability, need for a computing introduction, and overall course plan

What does CIT's AP CSA & CSP prep program look like?

Concept learning based on the current framework

AP CSA: Java syntax, classes & objects, data structures, algorithms, recursion, File I/O, dataset processing covered according to the latest College Board framework. AP CSP: includes computational thinking, data, the Internet, algorithms, and programming fundamentals.

Digital exam-environment practice tests

Students repeatedly take practice tests that mirror the Bluebook digital exam environment on CIT's in-house ExamPrep platform. An adaptive system automatically analyzes weak units to support efficient studying.

Targeted reinforcement of individual weaknesses

The format is set after consultation based on the student's level and goals, using either 1:1 or a small class. Instruction targets weak units, FRQ coding, question patterns, and time management.

Can't come to Apgujeong? 6-8 weeks of online 1:1 or small-group (1:n) intensive coaching right before the May digital exam

CIT is an in-person academy in Apgujeong, Seoul, but for students who need a final push right before the AP CSA exam, we offer 6-8 weeks of online 1:1 or small-group (1:n) intensive coaching right before the May digital exam. It runs with the same curriculum and instructors regardless of location.

A good fit for these students

  1. Students living outside central Seoul, such as in Bundang, Ilsan, or Incheon
  2. Korean students living in Singapore, Hong Kong, or the U.S. East Coast
  3. G10-G12 students who need intensive reinforcement right before the exam because school classes alone aren't enough
  4. Students who prepared with the old curriculum and need to switch to the new framework
  5. Students who haven't yet adjusted to the Bluebook digital environment

Online intensive coaching structure

  1. 2-3 weekly 1:1 live sessions (60-90 min)
  2. Short, focused mastery of the new framework (File I/O, datasets)
  3. ExamPrep digital practice tests + 1:1 FRQ code review with an instructor
  4. In-depth reinforcement of weak units (automated analysis report provided before each session)
  5. KakaoTalk channel question support through exam day
About online coaching

Online intensive coaching runs separately from the in-person Apgujeong classes, and a hybrid format (in-person classes + online reinforcement) is also available. Spots are limited, so we recommend reaching out at least two months before the exam.

How AP CS exams affect college admissions

AP course grades and exam scores can be part of a student's academic record, but colleges interpret them in the context of the school, course access, intended field, and the rest of the application. No AP score guarantees an admission result.

Weighted-GPA treatment varies by school, and AP credit policies vary by college. CIT does not decide those policies. We prioritize course preparation and only add a separate USACO path or student-owned AI project when it fits the student's workload and goals.

Frequently Asked Questions

How did AP CSA change in 2025-26?

Starting in the 2025-26 school year, College Board revised AP CSA: Inheritance and Polymorphism left the required scope, File I/O and Dataset Processing were added, and the exam moved to Bluebook. The revision year is historical context; use the official Course and Exam Description for the student's current exam year.

Was AP CSA Inheritance dropped from the exam scope?

Correct. With the 2025-26 revision, Inheritance and Polymorphism left the required exam scope. If you use older material, compare its units with the current College Board Course and Exam Description.

How do I prepare for the digital AP CSA exam?

The current AP CSA exam is fully digital in Bluebook. Use the official test preview to learn the Java input flow, study the current framework, and practice 42 multiple-choice questions and 4 FRQs in their respective 90-minute sections. Confirm the date and registration process in the official guidance for the student's exam year.

Where do international-school students in Korea take the AP CSA exam?

Test locations and outside-student registration vary by school, center, and year. Ask the school AP coordinator first. If the school does not register the student, check Fulbright Korea and College Board's current registration guidance for center availability, procedure, and deadlines. CIT is not a test center or registration provider.

What's the difference between AP CSA and AP CSP?

AP CSA focuses on Java programming and algorithms, while AP CSP covers broader computing concepts and includes the Create Task. CSA requires deeper Java coding; CSP is more accessible to beginners. Choose after checking school availability, current experience, workload and the target colleges' current requirements.

Do I need to learn Java in advance for AP CSA?

Prior Java experience helps, but it isn't required. CIT's AP CSA course starts from Java fundamentals and systematically covers everything in the exam scope. That said, we recommend securing enough prep time (six months or more).

How long should I prepare to aim for a 5 on AP CSA?

No course can guarantee a 5. Preparation time depends on current Java and algorithm skills, school-course coverage and weekly study capacity. Start with a timed diagnostic in the current format, then sequence concept review, multiple-choice practice and FRQs.

When is the best time to start preparing for the AP exam?

Use the student's exam-year school calendar and current Java readiness. A timed diagnostic during the preceding term leaves more room for concept study and FRQ practice; a student without Java experience may need a longer runway.

What is the AP CSA exam format?

The current AP CSA exam is a 3-hour fully digital exam in Bluebook. Section I has 42 multiple-choice questions in 90 minutes and is worth 55% of the score. Section II has 4 free-response questions in 90 minutes and is worth 45%. College Board can revise the format, so check the official exam page for the student's exam year.

Does the AP score affect GPA?

The AP exam score and the school GPA are separate, while weighted-GPA treatment varies by school. Check the school's current academic policy and each target college's current AP score or credit policy.

I can't come to Apgujeong. Can I prepare for AP CSA online?

Yes. CIT runs 6-8 weeks of online 1:1 or small-group (1:n) intensive coaching right before the May exam. Students outside central Seoul (Bundang, Ilsan, Incheon, etc.) and Korean students living in Singapore, Hong Kong, or the U.S. East Coast all study with the same curriculum regardless of location.
