Yes but how old will he be at the end of book 7? There is no way I 
can interpret the above to mean that the end of the last book 
absolutely positively most be on graduation day and not one bit 
later. Why would she wish to impose such a restriction on herself? I 
can't see her forcing a plot line to an unnatural premature ending 
just so last book covers only one year like the previous 6. Obviously 
book 7 being the last will have things about it that are different 
from the other 6.
