What is overall accuracy?

Overall Accuracy at the top of the Statistics page is your general success rate so far.

It reflects all the work in your account, not a single lesson or course. That is why one unusually good or bad lesson never makes it jump — it moves slowly over time. Deleting a course does not change it either.

Seeing a dash instead of a number? You have not answered any questions yet; the figure starts once you finish your first lesson.

So what is a good score? Accuracy is not a grade, it is a calibration signal.

• Consistently very high may mean the material is easy for you, so try raising your level.
• Noticeably low often means the fundamentals have not settled yet, and reviewing without rushing gets you further, faster.
• Somewhere in between means you are learning at a healthy pace.
