MIT OpenCourseWare courses on YouTube, ranked by total hours

Updated 2026-10-13 · 16 courses · totals are live

MIT OpenCourseWare puts whole MIT semesters on YouTube: the lectures as they were given, from 8.01 mechanics to 14.13 psychology and economics, with the problem sets and exams free on ocw.mit.edu. A course is listed by its MIT number, which is how most people search for it, and what neither the number nor the playlist tells you is how long the course takes to watch. A semester at MIT is about thirteen weeks of lectures, and on YouTube that is usually 20 to 35 hours of video.

This page covers MIT's physics, economics, chemistry, biology and psychology courses. MIT's computer science courses are in the university computer science hub, and its calculus and linear algebra in college math. The numbers next to each course are live totals from the playlist itself, ranked longest first. Click one to see every lecture, tick off what you've watched, and get a finish date.

From 6h 32m (MIT 8.20 Introduction to Special Relativity, January IAP 2021) to 1d 11h 54m (MIT 8.333 Statistical Mechanics I: Statistical Mechanics of Particles, Fall 2013).

How to take an MIT course from YouTube

  • Do the problem sets: the lectures are half the course. Each course's page on ocw.mit.edu has the problem sets, and usually the exams with solutions, so plan an hour or two of problems for every hour of lectures.
  • Pick by the number: the first digits are the department (8 physics, 14 economics, 5 chemistry, 7 biology, 9 brain and cognitive sciences, 15 management), and low numbers like 8.01 or 14.01 are first-year courses with nothing assumed.
  • At speed: lectures recorded in a hall have pauses and board work, so most people can watch them at 1.25× or 1.5×. The guide to watching at 1.5× and 2× has the numbers.

Finishing one

Open a course here, tick lectures as you watch them, and the remaining time updates. The planner turns the total into a dated schedule you can put on your calendar, and the guide to finishing before an exam has the method. For a lighter first pass at the same subjects, Crash Course covers physics, chemistry, economics and psychology in short episodes.
