How does Oxbridge consider sporting commitments?

During my GCSEs I trained for my sport 4 hours a day and came out with disappointing results (2 x 9, 2 x 8, 4 x 7, 6,4). With good predicted grades (having quit that sport) and being solid in other areas, would Cambridge still consider my GCSEs as on the lower side when making decisions? I understand it doesn’t fall into context in the usual sense but is it worth mentioning?

That was entirely your choice and wouldn't be considered contextually. Was this not a consideration when you were doing your training?

I would just reframe this with the fact that those are good grades, 4 A*s, 4 As, and 2 lower grades are nothing to sniff at
As above though that's not an extenuating circumstance, but unless you're applying to Oxford medicine I think it would not make a big difference?
Hopefully you didn't quit the sport because you thought you were doing poorly academically

Thank you!! I think people are misinterpreting what I mean by it being considered - I just want it to show hard work/commitment. Unfortunately I did quit as my parents were not happy with me and I had originally wanted to follow the sport through to a career (which is why the grades were lower). However I have really enjoyed my a levels so can see myself studying further. Anyway thank you for your positivity!!

In that case then they aren't really overly interested in non-academic activities like that (other unis may be slightly more interested in it). Generally if you were still doing it I probably wouldn't have recommended writing more than a passing reference to it unless you were applying to sports science or something.

Okay thank you! Should I mention it in my PS (which has little room left) or should I perhaps mention it to the teacher writing my reference?
