Common questions
When is the AP Cybersecurity exam?
AP Cybersecurity is a new College Board course effective Fall 2026, with the first AP exam in May 2027. CS++ built its full course early so students and teachers can start preparing now and build a strong foundation before the first exam.
Is the AP Cybersecurity course free?
Yes. Every lesson is free with a free account, and so is one full mock exam. Creating a CS++ account costs $0 — no credit card, and there is no paid registration tier. An optional $9.99 one-time lifetime membership unlocks mock exams 2-5, the full MCQ bank, and AI features. There is no subscription.
What does the AP Cybersecurity course cover?
The course covers all 5 College Board units: Introduction to Security, Securing Spaces, Securing Networks, Securing Devices, and Securing Applications and Data — including threats and risk, the CIA triad, network and device security, application security, and cryptography.
What is the AP Cybersecurity exam format?
The exam has two sections: 60 multiple-choice questions (70% of the score) and 1 Device Security Analysis free-response question (30% of the score), written in prose rather than code. The CS++ mock exams mirror this exact format.
Do I need to install anything to use the course?
No. The entire course, MCQ practice, flashcards, mock exams, and hands-on tools like Capture The Flag and SQL Detective run in your browser — no install and no login needed to start the free tools. It works on Chromebooks and any device.
