Free educational use

BrainyWave is free for personal learning and for teachers to use in class. You may print charts and lessons for your own or your students’ use. Please don’t copy the site, its lessons or its content to another website, app or publication without permission.

No guarantees

We work hard to keep every lesson correct and up to date, but we cannot promise the site is error-free, and we cannot promise any particular learning result, exam score or job outcome. Use your own judgement and, where it matters, check with a teacher.

Not professional advice

Knowledge articles and life-lesson pages are general information written simply. They are not medical, legal, financial or career advice.

Content and names

Book insights and people stories are original summaries written in our own words. Book titles, authors, films, talks and brands are mentioned only to identify them; BrainyWave is not affiliated with, sponsored by or endorsed by any of them. If you own rights in something and believe it is used here wrongly, write to us and we will act quickly.

External links

Links to other websites are provided for convenience. We do not control those sites and are not responsible for their content.

Changes

We may change or remove content and features at any time. Continued use of the site means you accept the current terms. Last updated: 6 October 2026.
