But I doubt whether you can do a full PPL with significantly less than 100 landings, or reach solo standard with significantly less than 50 landings.
When I was struggling for a couple of lessons with the flare I was getting really annoyed with myself. Never counted before but I had 41 total landings in my log book over a period of 7 weeks before my first solo so clearly my instructor was right and I was being too hard on myself!
