Hi faa2010,
These 4 are much easier than Op. 2, no.3:
1. Op. 10, no.1
2. Op. 10, no.2
3. Op. 14, no.1
4. Op. 14, no.2
Somewhat easier would be:
1. Op. 31, no.2
2. Op. 31, no.3
3. Op. 10, no.3
4. Op. 26
5. Op. 28
6. Op. 54
These are around the same level:
1. Op. 31, no.1
2. Op. 2 , no. 2
3. Op. 22
4. Op. 110
I hope I have been helpful, Joe.
