AP®︎/College Computer Science Principles
- Free
- No certificate
Khan Academy's AP/College Computer Science Principles course follows the topics of the AP CSP curriculum across ten units. Digital information covers bits, bytes, binary numbers, storing text, converting analog data and lossy versus lossless compression, followed by units on the Internet, programming, algorithms, data analysis and simulations. Later units deal with online data security and computing innovations, and the course closes with an exam preparation unit and a mapping to the AP CSP standards. The content is delivered as videos and articles with AP-aligned multiple-choice practice, and the page lists 63 skills that the site tracks from Not started to Mastered.
Each unit has quizzes and a unit test, and there is a course challenge for the whole course. Everything is free, with no paid tier and no certificate; taking the actual AP exam is a separate matter handled by the College Board and is not part of this course. No duration is stated.
