I started this topic just to tell the people on Brilliant.org about one of the greatest site I have seen. Since August (2012) I have been using a website called Coursera.org. It is a collaboration of several world renowned universities including names like Stanford, Univ of Toronto, Columbia Univ, California Institute of Technology, etc. These colleges and universities offer courses on different topic like Calculus, Programming, Biotechnology, Algorithms, Business, Health, Mathematical Thinking, Algebra, Earth Sciences, Physics and many more.

These courses are taught by one of the best professors in the field. These courses are absolutely free and you also get a certificate if you qualify all the quizzes, assignments, etc. In my opinion Coursera.org is better than MIT OCW, edX, Udacity, KhanAcademy and other free-education sources.

I would recommend you to take some of the following courses :

i) Calculus : Single Variable - University of Pennsylvania

ii) Analytical Combinatorics, Part I - Princeton University

iii) Analytical Combinatorics, Part II - Princeton University

iv) Linear and Discrete Optimization - Some European College(but course is in english)

TopNewestCoursera is indeed an amazing site founded by two Stanford professors. I have completed 9 courses there in the past 8 months and they are all really top notch. Besides some decent math they really have good computer science as well for people who are interested in that. Also udacity.com which came from Stanford is specifically about computer science right now and has some really creative great content.

Also check out MIT open courseware at http://ocw.mit.edu/index.htm where literally almost any course in higher math can be found and edX at edX.org which is like coursera with a few less courses so far but from Berkeley, Harvard, and MIT.

I did an introductory course on Python programming on Coursera once.Currently I am doing Waves and Optics from Rice University on EdX.It is a fantastic course and I would urge motivated high school students to try it. – Arif Ahmed · 2 years, 10 months ago

It is a great site. I have completed introduction to mathematical thinking with Keith Devlin and it was very helpful. I am currently enrolled in Astronomy and Calculus: Single Variable, both are great and I would highly recommend them. – Daniel Feinstein · 4 years, 7 months ago
