A somewhat chequered learning process.
Gliding solo at 16, first PPL thrash at age 27, second thrash at 42.
First thrash - 11:55 hours to Ex12, Ex13 with afato - there's no doubt that the next session would have been solo, but I had absolutely run out of dosh, then met Mrs Driver, then mortgage, kids, etc.
So at age 42,
1. 49:10
2. 1
3. Just under 12 months
4. About once per week, occasionally twice
5. 7:30
6. Unlike your other feedback, I've always found the flying very straightforward. Technical and Nav exams were easy for me, Met. more difficult but interesting. (Air Law a complete bore - completely irrational and hopelessly put together. All words and no ergonomics. No surprise that it took me 2 goes).
