IB Unlocked is an independent, student-led platform with a simple mission: make IB studying easier and more accessible, wherever you learn.
The IB can feel demanding. Finding an explanation that makes sense shouldn't add to the workload. We bring free, well-organized resources and simple study tools together so students can spend less time searching and more time understanding.
Every note is written by a student who has been through the course, and checked for clarity and accuracy before it's posted. Always check the syllabus and guidance from your teacher — student notes can contain errors.
There are no accounts. Your syllabus progress and focus sessions are saved only in your own browser. If you request a topic and leave your email, we only use it to tell you when the notes are up.
