You have to cover the full syllabus, this will include a fair amount of VFR flying. Although you covered this at PPL, even if you were going a modular route you would still have to do at least 15 hours visual flying, and you are tested to a far higher standard than you were at PPL.
You may see it as redoing, while your school will see it as advancing.
Why did you change from modular to integrated with the same school having already completed so much training? Seems an awful lot of money just to repeat training.
