That’s great! And maybe you are Grade 5 – I know you said you stopped for a while and forgot everything, but that doesn’t really happen. It might get rusty, but it’s still there somewhere, and only needs polishing up.
Consistency would be good. It’s hard to tell how pieces are graded. I like playing “good” studies because they can be enjoyable pieces but tend to be internally consistent in terms of difficulty, whereas a piece of music might be do-able at G4 level apart from a couple of notes that are more like G6 level.
