This app has not received enough ratings or reviews to display an overview.
The Mastery Map showed you which facts you get wrong. Now it shows how they are done.
• A fact card names the trick its fact is answered by, and opens the article that teaches it.
• It also shows what you actually answered when you got the fact wrong.
• Reading about an exercise now sits with the exercise, in its history.
• Entering an answer has been reworked, with a keypad laid out the way a calculator is.
• Answers can be sent by hand instead of automatically, and the field can show the answer's length. Both in Settings.
• Polish and bug fixes.
Keep training!
