Concept mastery

Concept mastery is a measure of how well you actually know a single idea, tracked over time as you study and test yourself.

Instead of one grade for a whole course, mastery breaks your knowledge into individual concepts and scores each one. A high score means you have answered it correctly and recently. A low or fading score means it is time to revisit.

Tracking mastery per concept tells you exactly what to study next, rather than re-reading everything evenly.

How StudyPDF does this

Bo keeps a mastery score for every concept in your course. Each quiz, exam, and flashcard updates it, and the scores fade over time so weak spots resurface.
