12+/13+ Late Transfer test: I can only comment on my experience. DC took both tests, failed to qualify for 12+ but qualified (with a strong score) for 13+. These were CEM tests, Verbal - Maths - Non Verbal, and computer based. DC said the timings were a lot tighter for these two tests and found it strange (although loves computers generally) to get used to answering on the screen. They do have paper/pencil for working out for some sections but not all, maths was definitely one of those and DC in the 13+ made use of it - actually filled the whole paper up with workings out, didn't want any silly mistakes this time!
We were lucky, DC qualified and was allocated a place at their chosen grammar school, initially the only one for Y9 entry, however another child (who'd qualified) got in by an oversubscription appeal. So just two entrants for that year. It is a risk on availability, however if you are happy to take that chance ... good luck in whatever decision you make
