Looking for general information about the test?
This test is open-book: you may use any and all non-human resources during the test, but the only humans to whom you may turn for help or from whom you may receive help are the course’s heads, which means that you may:
- browse and search the internet,
- review books,
- review questions and answers already posted on Ed,
- review the course’s own materials,
- use CS50 IDE or CS50 Sandbox, and
- email the course’s heads at email@example.com with questions, but
You may not:
- receive or solicit directly or indirectly any help from anyone other than the course’s heads.
Take care to review the course’s policy on academic honesty in its entirety. Note particularly, but not only, that
- looking at another individual’s work during the test is not reasonable and
- turning to humans (besides the course’s heads) for help or receiving help from humans (besides the course’s heads) during the test is not reasonable.
Unless otherwise noted, you may call any functions we’ve encountered this term in code that you write. You needn’t comment code that you write, but comments may help in cases of partial credit. If having difficulty with code, you may resort to pseudocode for potential partial credit.
Among the test’s aims is to assess your newfound comfort with the course’s material and your ability to apply the course’s lessons to familiar and unfamiliar problems. And most problems aspire to teach something new.
