Congratulations Sophia. Welll done!!
Now remember, never again "spinach and brussels sprouts". There is lots of healthy food out there, choose whatever pieces you enjoy!!
About the Bach piece, it is Piano Syllabus level 9. Completely outrageous of Alred's editor to put that in their book.
Have you heard of Piano Syllabus? You can check the level of pieces there, in case you wonder if a piece is too easy or too difficult for you. Of course, the level of a piece is always a subjective judgement, and not all pieces are in there, but I find it helpful.
