In A (→GE1) and FE there is no natural raising d1 into d1. In this context, it is undoubtedly Chopin's oversight, one of the most common. The natural was added in all 3 pupils' copies. In GE2 a flat was added in front of the upper note, which was corrected in GE3 (→GE4). EE has doubly erroneous version, caused probably by Chopin's manner of writing seconds vertically and not diagonally.

The lack of the natural raising a2 to a2 in the ending of the 1st trill in A (→GE1), FE and EE is probably Chopin's oversight. The sign was added in GE2 (→GE3→GE4).

The version of the 2nd half of the bar in A, FE and EE is rather erroneous, so the change inscribed into FEJ should be considered as a correction. The mistakes in the number of ledger lines are Chopin's most frequent errors.

We add the accidentals returning f2 and e2 on the 10th and 12th notes in the R.H., which were omitted in A, FE and EE. The additions were already made in GE (in GE1 only the natural next to f2) and EE2. It is a typical error of Chopin.
