It's possible to drop subjects at 14 in the UK; just because Harry 
etc have studied something previously, there is no reason to assume 
they must necessarily continue to do so post-14.
There will probably be 5 or so 'core subjects' which everyone must 
take, and all the remainder will effectively be 'electives'; whilst 
Harry has continued to study all his old subjects, it's possible that 
less 'successful' students (*coughs* Neville?  Crabbe and Goyle?) may 
drop old subjects, rather than take on new ones.
