Practice Problems

Below you’ll find practice programming problems for each “week”, or unit, of CS50. Use these as guided daily exercises, or as “end-of-week” checks for understanding. The development of these practice problems was led by Margaret Tanzosh, computer science teacher at New Explorations into Science, Technology, and Math, NYC.
