First flight 20.15 on 27 July. Finished PPL 19.45 on 21 August, 1964, with previous gliding experience, 23 years old. On Jackeroos at Thruxton, so no radio, no electrics, no brakes to distract. The PPL course began immediately after a 3 week post graduate zoology course, with exam, so study was not unfamiliar.
Go for it, as long as you hire after getting your PPL.
You'll get checked out for the conditions where you're renting.
Buying your own plane immediately wouldn't be a good idea.
