I first solo'ed today, it was a fantastic feeling! I found myself talking my way round the circuit, the most nerve racking bit was the takeoff. From my experience, once you get into the air, your training will take over and your flying skills will really come to light. I hope you enjoy your solo, I've been told I wont ever forget it, I'm sure it will be the same for you!
I also passed Air Law today with 90%, it turned out to be a very good day!
