FREE OR VERIFIED
CS50: is the free route enough?
The learning can be free. Payment changes verification, not the problem sets, final project or the requirement to finish them.
Start free. Pay for edX verification only when a school, employer or reimbursement process needs verified identity attached to completion.
SAME COURSE, DIFFERENT PROOF
Choose by the evidence required
Free CS50Course access, problem sets, final project and a free CS50 certificate after meeting requirements.
edX verifiedPaid identity-verified credential for situations that require third-party verification.
Neither yetTry Week 0 before buying proof that you enjoy the subject.
PAY IF
The verifier matters
- An employer or school explicitly asks for verified completion.
- Tuition reimbursement requires an eligible receipt or credential.
- You have confirmed how the credential will be used.
STAY FREE IF
The project is the evidence
- You are testing whether computer science fits.
- You can show the final project and explain the work.
- No decision-maker requires identity verification.
OFFICIAL REQUIREMENTS
Completion still requires the work
| Threshold | CS50 states that at least 70% is required on each problem set/lab and the final project for its certificate. |
|---|---|
| Free certificate | Issued by CS50 after the course requirements are met. |
| Verified certificate | Purchased through edX and attached to an identity-verification process. |
| Price | Confirm the current edX checkout before paying; certificate pricing can change. |
