Harvard’s CS50x 2026 offers free computer science learning and a free CS50 certificate for learners who complete the required work to the passing standard.
Certificate requirements
To qualify, learners must score at least 70% on every required problem set and the final project. Enrolling or watching lectures alone is not enough.
Free and paid options
The free CS50 certificate is distinct from the separate paid edX verified certificate. Neither should be presented here as Harvard academic credit or a guarantee of employment.
How to get started
Read the official CS50 certificate page and follow the linked course instructions. Use the current course submission calendar and check how deadlines or year transitions affect unfinished work. This is a learning guide to the 2026 course, not a claim that a new admissions process has opened.
