Moving to area and thinking of Ardingly for Yr8 DD. This means she would have to sit common entrance to enter senior school next year. Have no experience of independent system (expat, kids been in international schools)and no idea how rigorous these exams are. Want to avoid situation that DD has Yr 8 at one school only to fail and have to enter state school in Yr 9. No places at decent state schools in area or else would choose that now. Really need some advice on this - can anyone help please?
