The English A'Level system (Wales too and NI?) is unique as it is so incredibly narrow. Throughout Europe, with the 'Baccalauréat' system- students continue all subjects to 18/19- not just maths. They can specialise to some extent, and their main subjects count for me in final exams- but they have to pass them all at minimum level.
Both systems have pros and cons, as always- but the English system is far too narrow and probably the European model, too wide. I really must spend time understanding the Scottish system better, as it seems they strike a good and positive middle.
All students should continue to do maths, and also English- but not necessarily as GCSE or A'Level- but adapted to the students. All students should be able to cope with numeracy and understand statistics, and practical things like debt, etc.
