A friends child has moved to Bolingbroke for 6th form and shared this with me.

Reading between the lines 80 children are starting the Sixth Form, the majority have stayed on. The entry criteria for A level courses is high - at least a B at GCSE for all A levels but A or A* for academic A levels. This would say to me that a large number of children at Bolingbroke met their entry criteria and so results must have been very strong at the academic end of the school.
If you go to website you can read all the Courageous Hounds Newsletters - they seem to do an awful lot of "extras" for the children.
