It is easy to turn off the ranking mode. To do this, click on Teach. Next, go to the PIN number at the bottom left-hand side, and click on it.
A screen will appear, with the option: Show ranking. If you remove the check mark, the intermediate score will no longer be shown.
Do you want to show the ranking again? The feature can be turned back on in the same way as described above, but by placing a check mark in the box.
