mmzz our school always took the exams as linear, so all my DC (who took GCSEs in 2006, 2007, 2008, 2009, 2011, 2012, 2014) took them as linear with no retakes and they each took eleven or twelve, and all in the same year, as did all their peers. Not all schools opted for modular or for splitting subjects over different years. Perhaps that's why I don't see the changes as seismic. The content is tougher but that's the only change at our school, which wasn't alone in its approach. Doing only eight would be incredibly limiting educationally unless schools provided non examined subjects alongside examined subjects in the way some independents do - but I don't think that's the way things would go.
