I had, foolishly apparently, assumed that studying 3 A levels was still the norm
It probably is, for people who plan to go to university, which is probably more than it was 25/30 years ago. Who's saying it isn't?
But there's always been plenty of people who do vocational training, apprenticeships etc at 16, which can also be a good route. Many of the people I know, who did this, have been more successful than those who continued studying.
Plus it seems that, these days, more people do A levels than we did (I did mine in 1992, so it sounds like we're around the same age) and they do more of them. We all did 3 plus general studies but now it seems that 'the norm' if there is one, is to do at least 4 'real' A levels, ie not including general studies.
Plus the results are far higher these days. I got the second best results in our school, which was ABB. The best person got AAB, and both of us could have got into anywhere except Cambridge with those grades, even Oxford.
I don't know what the other girl did, but I horrified everyone by getting a job because I couldn't be arsed with university (I went a few years later on day release as a mature student and got a first so it worked out well in the end).
Now it seems like most students get a string of A* grades, so if A levels were indeed far tougher now, that would mean that today's young people work much harder, are more intelligent and/or are better educated than we were.
But to be honest, based on a lot of the graduates and general youth culture that's around, I'm not sure that's true.
