I hope your “Favorites” library is getting bigger and bigger! You don’t have to choose difficult songs for this, just pick a song that you think would be fun to play! See if you can get an 80% or above! Utilize those practice modes because they REALLY help! In fact, it’s one of my most favorite parts of the program, because it teaches you exactly how the really good pianists practice. That’s a skill most pianists don’t really learn until college, and you are learning it NOW.
HAVE FUN!
