sieglinde- DD1 is hoping for 10 A* and has stated that she will retake art if she gets anything below an A. She has v high standards, is bright and works like buggery.
Her brother on the other hand is a lazy, workshy little sod who just thinks that things will fall into his lap and that if you have to work for them they aren't work having. We have tried everything over the last 7 years- cajoling, explaining, bribing, punishing, allowing him to find his own work level for a year (HA!!). His results reflect this.
Both these children are the fruit of my loins, have been brought up in very similar ways. I've never expected anything less of Boy child than I have of the girls. He just isn't cut from the same cloth. I've had to revise downwards my inner hopes and expectations of him over the last 3-4 years whilst outwardly continuing to expect the best from him.
It doesn't matter really what I know about Oxbridge entrance- he has had the same information as DD1 and decided that it sounded too much like hard work; DD1 treats same information as a challenge and rises to it. We have expended as many resources and energy as we could trying to get DS to point in the right direction.
As a university friend (now a sec teacher) said recently, getting into Oxbridge (which incidentally both DH and I achieved) is not just about pure ability, it's also about managing to get your act together in time. DS did not manage this, DD1 might (and I hope so for her as that's what she wants.)
Incidentally, getting into Oxbridge also relies heavily on wise subject choices, so if anyone is contemplating them as an option for their DC, you must investigate extensively subject options before your child chooses GCSEs (ie year 8 or 9). Speak to the universities/colleges and ask them what the best subject combination would be for what your DC appears to be interested in. Do not let the school fob them off with crap non-subjects as both universities prefer solid traditional subjects at A level. I think that the reason my son got a university place at all despite dismal A level results is because he took three solid A levels.
