35 hrs at age 17.
Difficulty was - started training at 13, 1 lesson every 8 weeks (I was a paper boy!), got circuits out of the way but was WAY too young to solo, so had to move on to everything else dual , then at 16 and 10 months back to circuit practice in order to solo on my 17th bd then solo XC. Ended up with PPL at 47 hrs....phew!
What an epic paper delivery schedule it was!
