The Folkestone GS's are very under subscribed, much of this is because DC take the Dover test and get in there so don't bother with Folkestone. It is clearly not a 'mistake' the Dover and Folkestone tests are on the same date..... Not sure 'choosing' is a cheek actually. You'd have to choose at some point and can always appeal if you felt that way inclined should you not get allocated the one you had picked. I'd rather my child didn't have to sit multiple tests if I am honest.
The Folkestone GS's have had to react to changing conditions as in the previous years they only half fill (roughly) from Kent Test passing children and much of the rest of their intake are from appeals. At The Harvey recently the staff referred to their students being considered less able than in a typical GS but their 'Added Value' results are very good. Maybe some of that is the improvement
seen in their grades? GS's taking more able children have less room to improve those children to achieve top grades, against a school taking less able who go on to gain top scores in exams.
Anyway, I digress. It will be interesting to see how this evolves
