Hi !!

i have been playing for 8 months, taking 1 class a week.
I have just finished:
Scarlatti - K32
Bach - Prelude in C (WTC I)
Clementi - Sonatina Op.36 n°1 (all 3 movements)
I have also learned "Fur Elise" (still polishing it, sounds awful for the moment

)
I want to get into some Chopin, and i found out that pretty unknown Posth. Waltz in "A minor" (beautiful piece). I do not want to tackle something really out of my reach, tough.
I see this Waltz is graded as 4/5, and as you can see i have not played anything on this grade yet. I am a little intimidated because in another thread, Bernhard said that he would not assign any Chopin to someone with less than 2 years of piano.
To sum it up, do you beleive it is a good idea to begin working on this Waltz?
Thanks in advance for your advices,
