DD has a horrific time after half term with 7 exams (three days each have two exams), then 6 the following week, but they're more spread out. That will be 27 in all, counting each language part as individual exams (but not including the CS coursework thing, plus Classics coursework, as that's still old style A*-G), 11 subjects, plus she did Statistics last year as an extra. It's a stupid number of subjects (although my 6 were a ridiculously low number!), and totally unnecessary IMO.
So, no let up over half term here, although she is going to the cinema tomorrow ("we can go during school hours when it will be quieter!") as no exams
