My cousin is planning to move her dds from private to state school for sixth form because she feels it will give them a better chance of getting into Oxbridge. She and her husband both went and this is very important to them.
One of the schools she is looking at has a pretty good sixth form but is a big mixed comprehensive with poor gcse results. It is on Bristol's list of aspiring schools where contextual offers are made, I assume Oxford and Cambridge use the same/similar data.

Leaving aside what I personally think of this, is this likely to be successful?
I can't imagine universities have time to dig down and spot that the high gcse grades come from an expensive private school, so I suspect they will be taken at face value?
