I miss the exams so much, however ridiculous that sounds.
I'm now doing a-level maths and further maths, and I literally fantasise about the GCSE maths exams which I always finished in about half an hour. French and German exams were a breeze too, looking back. Nowadays my exams are absolutely brutal. I think about the FP3 paper and I want to cry, and the thought of writing those essays in my French and German papers fills me with dread.
My year in sixth form is only about 150 people, almost all of whom were in the school in lower years, so I don't really have the same longing for the camaraderie.
I do, however, miss the days when I was actually a functioning human being.
