I'm not getting agitated; just trying to point out that comparisons between different people, in different circumstances are meaningless.
If, for example, someone solos in 12 hours - is that 12 hours at 2 hours a day over six days? Or 1 hour a month over a year? The age of the student, the aircraft they are flying, the type of airfield (i.e. A/G Radio or Tower Control), the attitudes of the school and the attitude of the instructor.
Some schools will require certain exams to have been passed before solo; others not. Some schools will require training in ALL emergencies, PFLs, engine-offs, before solo.
The number of hours at which you solo is irrelevant - it's a number, that's all. It tells you nothing if you compare it to other people's.
The important thing is, that you're ready for it and have enough capacity to enjoy yourself and savour the moment without panicking at, for example, a strange instruction from ATC, or a light coming on or, in my case, a bird strike.
Cheers
