9 of the best free online education resources

Though the years spent from nursery school through to university may have seemed gruelling, they left us with a wealth of knowledge we use in our daily lives (and, hopefully, in our careers). But for many, entering the job market can mean an abrupt end to formal education. Unless you decide to quit your job and go back to school or add hours of night courses to your day, it can be hard to educate yourself on a new topic.

Luckily, there's good news for those with a desire to continue their education: There are many ways you can develop new skills and gain knowledge for free in your spare time. Many universities and other educational institutions offer free online courses, complete with tests, quizzes, reading material, study guides, and even textbooks. An actual degree from a university might cost you a pretty penny and leave you knee deep in student loans, but you can still further your education without forking out thousands.

Whether you're a painter who wants to learn how to code a website or a programmer who wants to learn more about art during the Age of Enlightenment, there are dozens of online resources. Even current students can benefit as educational resources complement studies open to those who don't have access to them or can't afford private tutoring.

We've rounded up a wide selection of tools that will help you educate yourself online, for free, in this article. So what are you waiting for – hit those virtual books…


The largest site on the Internet for web developers, W3Schools is a fantastic resource for those interested in brushing up on their web development skills – or learning them for the first time. Want to make your own website? W3Schools offers tutorials and references on a large range of subjects, including HTML, CSS, XML, JavaScript, PHP, SQL, and more.

W3Schools is a very thorough resource indeed. The HTML lessons, for example, are separated by subject, starting off with the most basic instruction and moving into XHTML. W3Schools offers a list of helpful references for each subject. Ever forget a tag name or need to know the colour name for the website you're building? W3Schools has it all. If you think you've got your HTML skills down pat, you can test how much you really know (and determine what you need to keep working on) in the HTML quiz.

Those dedicated enough to teach themselves an entire coding language can even receive certification. Users can apply for a certificate by paying an exam fee of $95 (£57). The exam is based entirely on the content of W3School's tutorials. Users that score at least 75 per cent on the exam (consisting of 70 multiple choice or true-or-false questions) get certified. Scoring 95 per cent or higher adds an Excellency Degree notation to the certificate.


We're guessing most of you have seen at least one TED Talk by now. The non-profit organisation started out as a conference in 1984 with the intention of "bringing together people from three worlds: Technology, Entertainment, Design." (It even saw one of the first Macintosh computer demos that year.) Fast-forwarding 28 years, TED now features a huge library of free, award-winning talks, with more added each week. Released under a Creative Commons license, the videos can be freely shared and reposted. TED speakers discuss a wide array of topics – from technology and design to science and culture – and present them in the most innovative and engaging ways possible within an 18-minute window of time. Past presenters include Microsoft's Bill Gates, Google founders Larry Page and Sergey Brin, a number of Nobel Prize winners, Amazon's Jeff Bezos, Stephen Hawking, Bill Clinton, and Jane Goodall.

Massachusetts Institute of Technology

You can use MIT to brush up on your university-level writing and reading skills without paying an exorbitant amount. The Massachusetts Institute of Technology has a slew of undergrad and graduate courses available online for free through its OpenCourseWare program. Over 2,000 courses cover architecture and planning, engineering, humanities, arts, social studies, science, and many other academic areas. Some of the most popular online classes include Introduction to Computer Science and Programming, Physics I: Classical Mechanics, Linear Algebra, Single Variable Calculus, and Introduction to C++. Some classes include interactive web demonstrations, streaming video lectures, and complete textbooks written by MIT professors. MIT's OpenCourseWare program lets users move through the lecture notes, suggested reading lists, and videos at their own pace.

iTunes U

iTunes U hosts content from more than 800 universities and distinguished organisations. Stanford, Yale, and Oxford are on the list, as well as MoMA, the New York Public Library, Public Radio International, and PBS stations. iTunes U offers audio and video of lectures, plus slideshows, PDFs, books, films, exhibit tours, and audio books. iTunes U, which supports both the PDF and ePub file formats, allows educators to distribute schedules, syllabi, lecture outlines, study guides, notes, maps, and even entire books. Don't worry if you don't have an iOS device; these formats work on any compatible e-reader. iTunes U offers material on nearly every topic, so whether you're looking to educate yourself on app development or just want a Shakespeare refresher, iTunes U can help.

Khan Academy

Sal Khan, former hedge fund analyst and creator of the non-profit Khan Academy, has made thousands of free educational videos and aims to continue until the day he dies. Hoping to make several tens of thousands of videos available in nearly every subject, Khan Academy currently covers a wide range of topics like maths, biology, chemistry, cosmology, astronomy, and physics. The site also dabbles in finance and history, and a partnership with Smarthistory added hundreds of art history videos to the library. The content is made in "digestible 10 to 20 minute chunks," and students are encouraged to complete practice exercises and assessments. The videos are made in a conversational style, taking a different approach to maths and science instruction than most are used to.

Peer 2 Peer University

Peer 2 Peer University, otherwise known as P2PU, is a grassroots open education project. Creating a "model for lifelong learning alongside traditional formal higher education," P2PU uses the Internet to make educational materials openly available for free. The courses are taught by volunteers who submit their course ideas and are guided by a group of community members and experts to create a syllabus. Students work together online to provide constructive feedback, completing tasks in both group and individual environments. Classes range in subject from Python programming to pencil drawing.

University of the People

Affiliated with the United Nation's Global Alliance for Information and Communication Technology and Development, the Clinton Global Initiative, and the Yale Law School Information Society Project, University of the People is the world's first tuition-free, non-profit, online academic institution. It aims to provide quality education to people around the world – especially those in developing countries. UoPeople, as it's otherwise known, works to "democratise higher education by providing universal access to college-level courses despite financial, geographic, or social constraints." Though it's not a fully accredited university, UoPeople is working to change that. UoPeople has accepted students of all age ranges from a vast amount of countries across the world.

To take courses through UoPeople, students must apply. Applicants have to prove high school completion, be 18 years or older, and be proficient in English. In order for the non-profit to stay afloat, students pay a one-time application processing fee ranging from $10 to $50 (£6 to £30) and an examination processing fee from $10 to $100 (£6 to £60). The fees are based on the applicant's place of residence – applicants from developing countries pay a lower amount.

Academic Earth

Academic Earth, an online video education site, offers courses and lectures from Yale, Harvard, Stanford, MIT, UC Berkeley, and Princeton in a user-friendly platform. With thousands of videos, Academic Earth covers a wide range of subjects, including art and architecture, astronomy, biology, business, economics, computer science, environmental studies, psychology, media studies, and law. Videos are graded, starting at a B and changing as users score each lecture. You can brush up on your US Civil War and Reconstruction Era history while riding the train to work. Users can also download QuickTime versions of lectures to watch while not connected to the Internet.


Intended for kindergarteners through twelfth graders (sixth form or college students) in the US, CK-12 is a non-profit organisation whose mission is to reduce the cost of textbook material in the K-12 market. To do that, it publishes open-licensed web-based textbooks, called FlexBooks, online for free. Much of the content is remedial, but many will benefit from reviewing subjects like calculus, trigonometry, and biology. For those in the US with children getting ready for the SAT, CK-12 also offers free SAT prep – saving parents hundreds of dollars on those expensive preparatory classes.

For those frustrated with ever-updating editions of expensive textbooks, CK-12's FlexBooks allow teachers to customise and create content by repurposing it to fit the curriculum. For example, when Pluto downgraded from the ninth planet to a dwarf planet, textbooks were rewritten and schools paid thousands to get the newest edition. With FlexBooks, teachers can go online and change a book for free.
