Your Harvard CS50 questions, answered
Which CS50 course should I start with?
Choose from the syllabus and prerequisites. CS50x provides broad foundations; the dedicated Python and SQL courses focus on those subjects.
Is a CS50 certificate free?
CS50x describes a free CS50 certificate after meeting its requirements. An edX verified certificate is a separate paid route. Check the rules of your chosen course.
Is CS50 the same as a Harvard degree?
No. An online course certificate is a different credential from a university degree. Check what the certificate actually states before using it professionally.
How should I plan my study time?
Allow time to attempt problems, debug and review concepts. Lecture duration alone does not describe the work needed to complete assignments.
