Terms of use
Last updated:
Free to learn
All learning content on this site is free for personal use: study with it, practice with it, use it in your classroom, and share links to any page. That is what it is for.
Ownership
The lessons, interactive widgets, practice generators, and design are the intellectual property of this project. You may not copy, scrape, republish, or redistribute substantial parts of the site — commercially or otherwise — without written permission. Linking is always welcome.
No warranty
This is an educational resource, provided “as is”. We work hard to keep every explanation and answer correct, but we cannot guarantee the site is error-free or that it fits any particular purpose, including any particular exam result.
Not affiliated with any test maker
This site helps students prepare for standardized tests but is independent: it is not affiliated with, endorsed by, or connected to any testing organization. Test names are trademarks of their respective owners and are used only to identify the exams.
Future paid tools
If and when optional paid tools launch, they will come with their own purchase terms, shown before you buy. Nothing that is free today will move behind a paywall.
Governing law
These terms are governed by the laws of Chile.
