OOP: A small Flintlet

While I remember..

When Harry and Cho are reminiscing about their first Quidditch match 
together (which takes place in POA), Cho refers to it as taking 
place 'in the third year'.

However, IIRC, she's a year above Harry: why would she use that 
phrase?

BTW, we need a L.O.O.N. to sort out all the ages of the members of 
Dumbledore's Army.  Luna is almost certainly in Ginny's year 
(because on the train she knows her and the others don't), but what 
about all the others?
