Switching which variations to study
Launch the course you want to study.
On the right side panel, click the three dots at the bottom-left and select 'Settings. '
In the settings pop-up, use the 'Study' drop-down menu to select 'All Moves' or your preferred option.
If you have already started learning the course with 'Key Moves,' you won't be prompted to review from move 1 for the variations you have already learned.
