my first guitar was also and Aria, the Aria ProII NK700, I loved it.
Hope you are getting at it and getting your finger tips hardened. I taught guitar for many years and the number 1 issue I ever found with people was the length of their finger nails on left hand. Has your teacher already covered this one??
Best of luck and feel free to ask anything.
I remember eventually figuring that out. I reckon I now cut my nails at least four times as often as I did before I started playing.
