Living Well / Free resources

Free learning & practical understanding

Choose one place to begin.

Build a little understanding through open lessons, course materials, textbooks, and visual demonstrations.

You can learn one useful thing without enrolling in a complete program. Choose a question you would like to answer, then match the resource to the size of that question. A plain tutorial may be more useful today than a university lecture series, while a textbook can provide a reference to return to.

Start with: LearnFree: everyday skills. Choose one tutorial that matches a task you actually need to do.

Take what is useful, thoughtfully.

Open materials are not automatically current in every detail, and access to a course is not the same as enrollment for academic credit. Check the level, date, and any account requirements. After reading, explain one idea in your own words or try one low-stakes example before moving on.

Selections are based on public source review, not a claim that Nolan uses every resource or belongs to the organizations listed.
