Book more lessons
I booked two sometimes three lessons a week, and probably used about half with the rest cancelled due to weather and the odd technical problem.
If you can manage to get a run of lessons by taking a few days holiday or over a long weekend, you find you can make a lot of progress.
Even with our weather, the PPL course can be completed within a year at weekends
If flights are cancelled, try to spend the time on ground studies/theory exams
