Hi aegeangull,
I am a modular student and I am planning to join Pilot Training Network next year for my flight training. Am I am not taking part to the ground school but I had the opportunity to talk to two former students (Modular and Integrated) and both have told me that they had a really good experience with both the flight training and the theory classes. Furthermore I have visited Rostock where the basic flying and instrument flying is held and the facilites are really good. The airport is quite far from the city and it is like staying in the country side but the accomodation are near the airport and the students told me that it is fine to stay there during the training as you live with other students.
