I am fed up with those people who bleat on about how children are either talented academically or not and about how IQ is largely inherited.
I believe extreme talent someone may be born with eg that 16 year old black swimmer, however, all you need to do is look at private schools to see that drumming exam technique into someone will lead to good grades.
I believe there are some children who are genuinely academically gifted but they are few and far between. All other children fall somewhere on a spectrum where given the right encouragement and environment can do well.
Our children are all doing well at school but I don't believe it is down to me and DH.
