I don't *have* any A-levels, so I wouldn't know what is or isn't
included there.
(You get to choose which ones you want to do though, right?)

Yep. As scott said, any education beyond 16 is optional in the UK. If you were
so inclined, there'd be nothing to stop you doing a maths A-level now - many
people do. I suspect you'd find much of it relatively easy, and you'd definitely
find the calculus interesting and useful! No idea what it might cost tho.

I think the structure of A-levels changed in 2000 (more continuous assessment
instead of oodles of exams after 2 years), but I expect it's broadly the same.

Indeed. And of course many universities have the word 'college' in their names,
especially the younger ex-polytechnics, confusing the issue still further!

...all of which seems to support my assessment of "calculus is no longer
part of standard school education".

Which just goes to show the problem I have with 90% of all matehmatical
notation. It's so utterly inconsistent that even something like (f(f(x))) is
ambiguous.

FAIL.
The correct query is of course
http://www.wolframalpha.com/input/?i=derivative+of+f[f[x]]
Nice try tho. :-P

Several millennia of mathematical discoveries, all made by different
people in different places, and apparently several of them discovered
the same or similar things, but gave them different names - or gave them
names which clash with existing but inrelated things they didn't know about.
Just for giggles: how many meanings can you find for "normal"?
There's the normal distribution, normal vectors, a normed space...

Yes. I didn't see there were 50 responses before I posted that. :-)

Apparently so. One of the reasons I hate mathematical notation.

Wolfram at least have come up with a consistent, non-ambiguous notation.
In their notation, a(b)c unambiguously means the product a*b*c, and
a[b]c unambiguously means that b is the argument of function a,
multiplied by c. This is partly how Mathematica is able to determine
precisely what you meant.
Of course, nobody else uses this notation. And while *Mathematica*
rigorously follows it, *Alpha* attempts to "guess" what you mean. So in
the case above, it takes "f(f(x))" and guessees that you maybe mean "f *
f[x]", which isn't quite right. (This is what happens when computers try
to guess things...)
