Browse every course →What is One Dollar School?+
One Dollar School is a worldwide online library of practical answers and short mini-courses. Every article is free to read, and you go deeper with a complete course that costs one dollar instead of a monthly subscription.
How much does a course cost?+
One mini-course costs one credit. Credits are sold in bundles that start at one dollar, they never expire, and nothing renews automatically. There is no recurring subscription anywhere on the site.
Can I read the answers without paying?+
Yes. Every published answer is free and complete — the full article, the table of contents and the follow-up questions. You only pay if you want the mini-course that goes further into the subject.
Do I need an account to read?+
No account is needed to read the library. A free account adds saved reading, course progress and a starting credit so you can try a full course.
What can I learn at One Dollar School?+
Money and budgeting, business, technology, home repairs, cooking and food, careers and study, health basics and everyday practical skills. New answers and courses are published every week.
How long does a mini-course take?+
Most mini-courses are three short lessons and take between twenty minutes and an hour. Each one ends with a simple tool you can work through so the lesson turns into something you have actually done.
Is there a free lesson?+
Yes. The first lesson of every course is open to anyone, and the course page shows the full lesson list, the outcomes and the tool before you spend anything.
How is this different from other course platforms?+
One question, one page, one price. There are no subscriptions, no bundles of filler content and no paywall on the answer itself — the course is a short, practical extra written by someone who does the work.
