Just looking at the results of my local comp.
The highest scoring GCSE candidate got 4A (inc Maths & Physics) and 7As. Would they automatically be excluded by Oxbrudge selection computers because of not having enough A?
Bear in mind, this girl's results are significantly better than the rest of the year, the two next best have 2A and 1A, after that there are a couple of all As and then about 5 with a mix of A/B etc.
The school is normally well under the national average.
