CS50: Introduction to Computer Science is Harvard’s famously challenging beginner CS course, offered free online, and it’s become a rite of passage for many aspiring programmers. Through engaging lectures, problem sets, and projects, students tackle topics like algorithms, C programming, Python, web development, and data structures, with a strong emphasis on problem-solving and perseverance. Created and taught by Professor David Malan and his team, the course is demanding but carefully scaffolded, making it accessible to motivated high schoolers and adults willing to put in serious time. Parents appreciate the world-class instruction at zero tuition cost, though there is an option to pay for a certificate. It’s not a casual elective; we recommend treating it as a major commitment equivalent to a full-credit class.
