Good for you!
You're at a great stage in anyones flying career; nobody expects too much of you and everything is new! You soon pick things up, and what may appear overload now will soon be second nature. My advice, you can't beat just sitting in the aeroplane and getting used to where everything is, also going through all the stages of the flight over and over in your mind. Don't be afraid to ask if it's ok to just go and sit in the aeroplane when it's not in use ... it might sound silly, but it really is a worthwhile excercise ... actually it's hangar flying that keeps all us PFA builders going as well!!!
