Frequently asked questions

Not at all. Every subject starts from zero — no prior knowledge assumed. Module 1 of each subject begins with the most foundational concepts and builds progressively from there. The only requirement is curiosity.

Each module is designed to take 15–30 minutes. Some are shorter, some run a bit longer depending on the complexity of the topic. There's no timer — read at your own pace.

No — and that's intentional. University courses are built around grades, exams, and credentials. STEM For Adults is built around understanding. There are no tests, no grades, no certificates. Just clear explanations of how the world works, for people who are curious about it.

The depth is real though. We don't dumb things down — we just explain them properly.

There's no "behind" here. Your progress is saved automatically and syncs across devices. Pick up exactly where you left off, whether it's tomorrow or six months from now. Your access never expires.

Yes — all subject sites are fully responsive and work on any device. An iOS app is also in development for an even better mobile experience.

Module 1 of every subject is completely free — no account required. Just go to any subject site and start reading. If you want to continue beyond Module 1, you'll need to create a free account and purchase the subject.

Yes. One account, one login, works across all six subject sites. Your purchases, progress, and profile are all in one place at any subject's account page.

We have no plans to shut down — but in the unlikely event that happens, we would provide advance notice and export options for all content you've purchased. We believe you should own what you pay for.

Yes, genuinely. One payment, permanent access. No monthly fee, no renewal reminder, no subscription that quietly charges your card. This is a founding commitment of STEM For Adults and will never change.

The $99.99 Full Platform purchase gives you permanent access to every subject currently available, plus every subject we add in the future. One payment, forever. If we release Mathematics next year, it's yours automatically.

All sales are final. Because Module 1 of every subject is free before you buy, you can genuinely try before committing. If you have a technical issue or were charged in error, contact us at support@stemforadults.com and we'll sort it out. See our full Refund Policy.

Yes. Payments are processed by Stripe — one of the world's most trusted payment processors. We never see or store your card number. Stripe is PCI DSS compliant.

Every subject includes the full learning path plus extras specific to that subject — Deep Dives (long-form essays on fascinating topics), a Hall of Fame of the scientists who built the field, and subject-specific databases like the Elements Database for Chemistry, the Celestial Objects explorer for Astronomy, or the Life Database for Biology.

Yes. We regularly add new Deep Dives and additional content to existing subjects. If you've purchased a subject, all new content for that subject is yours automatically at no extra cost.

Mathematics is currently in development. If you purchase The Full Platform ($99.99), you'll get access to Mathematics automatically when it launches — no additional payment needed.
