you should talk to your teacher if you have one? she/he would have a better idea of what you are capable off.
well, to give us an idea of your level what other pieces are you learning now?
not even taking the fact into consideration that you have only learnt the piano for 3 yrs, there if no particular order that everyone learns the etudes in. Everyone has their own strengths and weaknesses so the order of which the etudes are learnt in is always different.
what my teacher believes is that even learning one page of each etude can benefit an individual if he/she is at that stage where they can't handle the whole etude yet. Even if you can't handle it at full speed, still if the technique is learnt correctly and taught properly the individual can benefit alot.
for I myself, before I even started, I played around with a few like op.10 no.4,5,8 and op.25 no.1,7 and 11. Would have liked to start off with op.10 no.4 or 5 but after sampling each for about 2 weeks I could'nt go any further and decided to start off with op.10 no.8. Took a year to master it but it was well worth the effort. Started op.10 no.5 in in may'07 but I have put it aside as I can't handle the last few bars now. Currently finishing op.10 no.4 and learning the rest slowly.
