You need to try out the piece in order to know if you are ready for it. It's like looking at a pair of shoes and wondering if they will fit without putting them on your feet. Don't obsess over page 1 without sampling the rest of the piece. Try out a few measures from various parts. If you do decide to learn it, don't learn linearly from beginning to end. Be goal oriented and start with the most difficult parts of the piece. I'd actually suggest working on your sight reading. Do you play in ensembles, accompany singers or instrumentalists? It's a great way to make music and improve your sight reading.
try the last few pages, before the coda.
Thanks! Do you think this will give me a better idea of suitability than just plunging straight into the coda or continuing from the beginning?
