I do think that whilst we can sit and say able students will be able to look up the process easily etc and find it (which is true and let's face it kids are more tech savvy than many of their parents) that if they are schooled in any environment where Oxbridge applications are not the norm that although they can access the info easily enough were they to look for it, it may never even cross their minds that they should be looking for this information until way too late in the process.
Yes if they have a genuine interest they may have already engaged in super curricular. However in an environment where extra is being pushed rather than super they may not realise. So sometimes it is precisely the type of applicant who would ebenfit from UNIQ that misses out on the opportunity it would give them. As I said up thread Oxbridge do seem to be trying to get to students earlier and have started including some year 10/11 stuff in a hope (I assume) to let high achievers realise there is a route to be followed and to alert them to it earlier.
Goodbye - whilst I appreciate DD4 looked up and found her masterclass off her own back I suspect that possibly due to her siblings having been down that route she may have looked earlier than general applicants might have or been aware vaguely that there were such things (and I am in no way knocking her initiative in seeking it out). Also at her superselective which appears to have a hands off approach there will be other students discussing what masterclasses they are all attending, what open days etc. At a bog standard such conversations may not be the norm. So maybe a student at a regular school with an over invested mum (like me) may have spotted these on Mumsnet and helped guide the student, but there will be so many who will be saying the school will guide them, the school knows best which is, of course, simply not always the case and indeed there is unfortunately the "not for the likes of you brigade" still out there.
I know of and have heard of grammar school students who do access UNIQ because of their ACORN/POLAR postcodes.
Let's face it too many parents are still under the mistaken impression that if the student gets all As (or equivalent) for their gcses and are predicted all As for their A levels that they will automatically get into Oxbridge, which is clearly untrue. When they don't they simply can't believe that "Johnny" didn't get in. Who did then etc? I have seen it so many times in real life and on similar threads on Mumsnet.
I am sure as parents that we have all been told - well its ok for you your DS/DD will get in - when we (from either looking at stats or reading tales of applications on here) know that in most cases you have a 5 to 1 chance of a place even with stellar grades.
Some DCs get this and some don't. My own will be taking a punt - if you don't try you won't get an offer but also is very keen on his other non Oxbridge "top" choice and I suspect in a way would be more gutted to not get an offer from that uni than were he to fail to secure an Oxford offer due to the odds!
I suspect also that by the time I post this (as it seems quite long and has been subject to interruptions) that all my points will have already been made and in a more eloquent manner!
