Someone I know took the best part of 80 hours last year to get his ppl with the aim being to continue on to cpl level. Strikes me that he is being milked by the school that he is at. He was in a hurry and was doing 4 hour days (far too much imho if you have no prior flying experience) and it appears from talking to him that no one advised him against doing so much.
I believe the 80 hours included minimal solo flight which will then impact on cost of gaining a twin turbine rating (due to needing to meet the minimum PIC time) should he continue.
If you want to become a cpl then 60 hours over a reasonable timescale should be more than enough before questions should be asked and a second opinion sought.
