This is CS50 (aka CS50x through edX).

Harvard University's introduction to the intellectual enterprises of computer science and the art of programming.

Demanding, but definitely doable. Social, but educational. A focused topic, but broadly applicable skills. CS50 is the quintessential Harvard (and Yale!) course.
