Me and my wife have been debating about if it would be worth sending our children to a secondary private school in order for them to recieve the best STEM education available. 
Both of them are very science oriented and we are a STEM-centred family. Parents of children who sent their children to private schools, how would you say their STEM (Science, Technology and Maths) education is compared to state schools?
Do you do/buy anything outside of the classroom to maximise their learning/attainment?
