well it took me 45hrs including the flight test, solo-ing after 8hrs.
What i wud say is relax and enjoy that way you are more likely to take in what you are being taught and probably learn quicker.
The PPL imho is a licence to learn. The course teaches you how to pass the test and then you realy learn how to fly.
One of the draws to flying is that you are constantly learning if you are a 45hr PPL or 10 000 CPL, IR , ME, MCC, FI and any other rating under the sun!
Just a little note: PPL requirements
45 hrs total time,
25hrs dual instruction, to include: 2hrs spin stall awareness and 2hrs instrument,
10hrs solo to include 5hrs cross country and a cross country of greater than 150nm with 2 full stop landings (at different aerodromes to your base)
Enjoy mate
Buckle up
