Usful of Quick settings

Do you think is there any difference between grades(Easy, Medium and Hard) of quick settings ?
As for me , I really couldn't find anything. And by the way my question concerne Spanish Rocket.

¡Hola IzsoA!

There is indeed a difference between the "easy," "medium," and "hard" recording settings, although it may not be easy to see it if your pronunciation is good. 

For the "easy" setting, you need to be at least 80% accurate to get a green rating on your recording. For the "medium" setting, you need to be at least 90% accurate, and for the "hard" setting, you need to be at least 95% accurate.

I hope that this is helpful! Do let me know if you still have any questions!

Hasta la próxima,
