At DS's school they have to get 8 of which four must be at least As, a science subject and Maths and English at A*-C - they aren't allowed to do A Levels in the subjects unless they've got at least an A grade.
Hence the need for a back-up option...just in case. Quadratilla it is reassuring to know there is one BUT I'm not sure DS will see it that way. Let's just hope it's not going to be an issue for either of our DC.
I was thinking back to my own 'R'(esults) Day - many many moons ago. I am not sure I really had the faintest clue how I was going to do (I didn't do brilliantly - did much, much better in A Levels). I don't think we had scrutinised grade boundaries to work towards and not even particularly convinced that we were given projected grades. And even at a grammar school the grades to get into the sixth form were standard (rather than inflated) ones.
There does seem to be so much more pressure on the DC these days...
