Poring over courses again for DS1 who will apply for Maths next time round, it has occurred to me - why all these four year courses? They didn't exist, I don't think, in my day, or if they did they were much less common. I could be wrong as I studied Law and just didn't look at science courses. But is it a new thing? And why? (And is it evidence that A levels just aren't sending people to start courses at the right level, so the unis are having to pick up the slack?)
