How to work through the CS50x: Introduction to Computer Science syllabus
The outline on this page is arranged the way the syllabus itself is: subject, then chapter, then topic, then sub-topic. That last level is what most study plans skip, and it is where coverage actually goes wrong — a chapter marked "done" often has three sub-topics inside it that were never touched.
Weight your plan accordingly: Programming in C carries 21 topics while Artificial Intelligence carries 8. Giving both the same number of weeks is the most common planning mistake for CS50x: Introduction to Computer Science.
The ~85 hour estimate above is a first pass only: roughly 45 minutes per topic plus 12 minutes per sub-topic. Revision cycles, past papers and mocks sit on top of that number.
