DON'T PANIC!! When you're close to solo and you know it, the mind starts trying to jump ahead to 'bridge the gap'.
You'll probably do an absolute greaser of a landing on your next lesson and then everything will be fine!! All the guy wants to know is that you're going to come back :-
a. Alive
b. With a rentable aircraft
c. With the same number of take offs and landings in your log book!
I managed to survive first solo 3 times (once in a glider at 16, once in Canada at 38 and once in UK at 39); it doesn't get any easier; in fact, it gets more difficcult, as you know the signs of when they're about to send you!!
Good luck for Friday.
