Narrative:

I entered the taxiway at spot 13 to runway 31. First time I was using runway 31. While I was doing the taxi checklist, I entered runway 31. I didn't notice, and when I was going to start the before takeoff checklist, I was ordered to taxi back to the flight school and tell my instructor to call ATC because of runway incursion.
