26 Best Online Courses to Take in 2026 (and How to Access Them Anywhere)
Oxford Business News Editorial · Updated July 5, 2026
Quick answer
These are 26 genuinely useful online courses across AI, coding, business and design — most of them free or free to audit. 26 of them sit on platforms that are blocked or limited in mainland China (YouTube, Google, ChatGPT), so we’ve flagged each course’s access and how a VPN restores it.
Open Mostly open VPN in China — access from mainland China
Every course below links to its official page. We’ve grouped them by subject and, for each, noted whether you can reach it from a restricted region. Where a platform is blocked, connecting a VPN to another country is the standard fix — see our best VPN for online learning guide.

Studying from China or a restricted network?
Roughly a third of the courses above rely on YouTube, Google or ChatGPT — all blocked in mainland China. A VPN routes your connection through another country so the videos play, the labs load and the AI tools work. These are the two we recommend for learners; see the full ranking.

Frequently asked questions
Which online courses are worth taking in 2026?+
It depends on your goal, but the highest-return picks right now are AI and data (the Machine Learning Specialization, fast.ai, Google Data Analytics), computer science (Harvard CS50x, freeCodeCamp), and recognised career certificates from Google and Meta on Coursera. Many of the best are free or free to audit.
Why can’t I access some of these courses in China?+
Several sit on platforms blocked in mainland China: YouTube (which hosts fast.ai, freeCodeCamp and many lecture videos), Google services (Kaggle, some course labs) and OpenAI/ChatGPT (needed for prompt-engineering courses). Connecting a VPN to another country restores access to all of them.
Are the free courses actually free?+
Yes. fast.ai, freeCodeCamp, The Odin Project, MIT OpenCourseWare, Khan Academy and Kaggle Learn are genuinely free. On Coursera and edX you can audit many courses free and pay only if you want the certificate.
Which VPN is best for reaching blocked course platforms?+
For students we recommend NordVPN (fastest for streaming lecture video) or ZoogVPN (cheapest, unlimited devices). Both reach the platforms these courses use. See our full ranking of the best VPNs for online learning.
