Tansie well, you must be in our area somewhere, this is how it has been for us:
I think we have done 99% of the actual subject advice for our DD (I may be wrong though)
They have had the colleges round for a 'post 16' evening so you could see what was available, plus a talk on apprenticeships. Plus they've had guidance with personal statements. Facilitating subjects may have been mentioned as 'look what you might want to do later and check you are doing acceptable subjects'.
She has had an interview with the careers advisor at school. But I understand that was more DD saying what she was thinking of, and advisor looking at predicted grades and saying 'yes that should be OK'. Which was as much help as a chocolate teapot really (as I think predictions are too high).
I am currently trying to word emails to some of DD's teachers to ask what they think about her doing A levels in their subjects, as I think parents evening next month is a) too late and b) not the right place. (This is maybe a problem of the Hants system, their GCSE teachers aren't also the A level ones).
However maybe there has been more advice available and DD hasn't been mentioning it / accessing it as she is getting good advice from us!
Particularly unclear to me is the new all-through A levels (eg English), what if you may want to stop after 1 year.
Also, no one seems to be explicitly saying that you should be at least getting Bs in the subjects you want to continue with (some subjects e.g. Languages and sciences do, but not as a general statement).
