I am in London with lots of secondary choices. There are a few schools which have excellent GCSE results but are undersubscribed and the only reason I can see vs the oversubscribed schools is that the undersubscribed schools (with better GCSE results) only go up to GCSE, there is no 6th form.
There are plenty of 6th form colleges in London. So what am I missing? Would I be crazy to consider a school that only goes up to GCSE?
