DS goes to a school where approx 1/4 go to Oxbridge. Even if the quarter are drawn from the top half, DS would be lucky to scrape into the top half.
Also, he got a 6 for one of his GCSEs and don't Oxbridge look for straight 8s and 9s as a basic first screen on candidates?
Then there is the fact that DS is just not ambitious. He is easy going and tends to wait his turn for things ( ie wait to be offered rather than go out and get). He doesn't set himself goals and strive to reach them, but rather drifts along doing what other people (teachers, parents) tell him to do.
As a way of being, it has meant that he has done well academically until now because he's done what the teachers requested, but adult life isn't a well-laid path that you just have to amble along. Sometimes there isn't a place for everyone who wants it, but DS just has no idea how to compete, and if someone else gets what would have been DS's in a fair world, DS just looks upset and moves on, but he never asks himself how it happened and what he could have done to prevent it.
Do I sound frustrated with him??!
