If I had known what I know now. I would have gone to USA or Spain to do my PPL. I stuck at a flying school that seems to just add more training hours for no apparent reason and the good part is that you can either leave or stick it out. there is no 3rd way around it once you are majority of the way through your training. You can complain to CAA about the school but Caa have no time for these complaints. Weather can play a major part in consistency (as pointed in a comment above), so going to Spain or USA is a much much better option. Yes, there are costs for accommodation, food travel etc. but you will firstly get a license quicker and in a timely manner.
