And I'm amazed a language A-level could be a "doss"! I thought they were the only fairly hard / not too badly dumbed down subjects left.
My 6th form timetabled things so I had either one or two free hours a day (out of the 5 total), with the rest being lessons I had to attend. So fitting a fourth A-level in would be quite possible, and a fifth too if I wanted to do a lot of work in my own time rather than being taught, but 8 would be impossible unless the courses were run with a LOT less teaching/contact time - and a lot of students wouldn't be able to cope with that, if the difficulty level was still about the same. I'm sure I couldn't have. Getting A grades wasn't THAT hard, but almost tripling my workload and the amount I needed to learn/know/write coursework for/etc would not have been feasible, that's for sure.
