Six years ago, universities like MIT and Stanford first opened up free online courses to the public. Today, more than 800 schools around the world have created thousands of free online courses.
You can also go to Class Central’s homepage to find many free courses available up to 10000 from top universities.
I’ve sorted these courses into the following categories based on their difficulty level as well as 3 parts of this topic:
The first sections will be for beginners(part 1.1, part 1.2), the second will be for those who are looking for intermediate courses(part 2.1, part 2.2) and the rest will be for advanced courses(part 3.1, part 3.2). All of these are aggregated in 250 free courses.
In this part I will introduce you to the courses that are suitable for intermediate learners, if you are looking for beginner courses click here, advanced courses click here.
