Narrative:

Second day of training for commercial rating (sel). I was given taxi instructions by lgb ground, which I did not understand due to the fact he gave it too fast, although I copied instructions in writing it took 3 times. I normally operate in a very low density airport (class D) in guam and was rather tensed at the heavy ground and ATC communications at lgb. While I was trying to identify the taxiway on my map, I inadvertently taxied on the active runway. The tower did not see me until I was on the runway and before I could inform the tower of my intrusion, they spotted me and told me to stop. He then advised me to do a 180 degree back to the taxiway he had previously instructed me to go and informed me to call him.
