MIT Economics Course

The MIT has the best graduate economic program, and its undergrad program is definitely in the top 3. The faculty is technical-oriented, which means a lot of math, so you'll be well prepared.

The list of requirements included in a syllabus of each course says what other courses you must complete before approaching this one. So, you'll know your learning path in advance.

Each course includes lecture notes and recommended literature.

I'd also keep in mind that while you save money learning this way, the process is quite difficult (especially due to solving math problems alone) and puts you out of sync with institutional aspects of formal education. Like, it's harder to enroll in a grad program or get an advantage in employment.
