That sort of intensive programme only suits a small amount of people and generally most students really aren't ready for a licence in 3-4 weeks.
Sometimes, this can work against them and damage confidence. I have seen students just freeze when you ask them for a basic plan if XXX happened. They were so fixated on getting solo in XXhrs, the numbers on the PLOG flown, or the PPL finished in time, that being safe and the bigger picture were binned in their mind, just to get the next exercise ticked off.
Over confidence was another issue, causing infringements or busting into an away airfield circuit the wrong way, because they didn't take the time to review their plan - or didn't think they needed to.
I guess my point is that rushing through doesn't always allow the brain to process what is has actually seen. A days rest to replay the flight and read the debrief comments and prepare for the next lesson pays off with the end product. There are no medals for a 3 week PPL.
