DS1 ( non selective state school but in a leafy green suburb) is looking to apply for Computer Science at Cambridge next year ( Y12 currently) . He is researching his application and compiling all his super curricular achievements but has noted that private school kids are far more likely to have competed in maths challenges and olympiads - his school offered Bebras one year in Y7 and that is about it - his school have never entered anything else. Do the admissions teams take that into account, that his peers at private and grammar school will have taken part in so many more events that state schools tend not to enter? He is getting quite worried about it. TIA
