I flew twice a day, four days a week for four weeks when I did my PPL.
I loved it, everything sank in & stayed put, not going days/weeks between study sessions and lessons really made everything stick.
On the other hand, for those 4 weeks I had no life, my friends thought I had been sucked into a black hole, and I did *nothing* but fly and study.
It totally depends on your personality and how much of your life you're willing/able to give up.
