Do you have a source? I can't imagine them effectively deleting their entire current database and creating a new one from scratch. It would make more sense that they'd recycle the current ECQB6.0 questions which are still in line with the new syllabus LO's, besides adding new ones ofcourse.
The past few year's they have deleted, modified and added questions according to the newer LO's, you're telling me that they threw it all away?
Regarding the books I ment major providers to flightschools like CAE, Nordian, Jeppesen etc. No disrespect, I have your book and I like it.
