GCSEs for Oxford Physics

Does anyone know what the average gcses roughly are for oxford physics applicants and how important they are when applying? Like I have 8A*s and 3As, would that be considered good, bad or just average?
Thanks

For reference, I applied in 2015 for 2016 entry, with 6 A*s at GCSE, AAAB (including 98% maths, 95% further maths, 94% physics) and predictions of a further AA at AS (chemistry and additional further maths) and A*A*A* at A level.

I scored one mark under the interview threshold on the PAT. If your grades are "good", they will interview you anyway if you marginally miss the PAT cut off. I was not invited to interview, so my grades were not considered "good". I'd suggest this would place your GCSEs as a similar level - slightly above average, compared to mine being slightly below (as my AS and A level grades could not be better - AAAAAB and A*A*A* - so it must have been my GCSE grades which brought my application down.)
