Sorry to rain on any parades, but there is an off cannon reason for 
Hermione not to be able to attend that class which is pretty 
infallible.

She in informed by Ron and Harry she missed charms.  She uses the 
time turner to go back and attend that class.  So why would Ron and 
Harry tell her she missed it.  They wouldn't, because she wouldn't 
have missed it.

When travelling back in time the one thing you absolutely CANNOT do 
is invalidate your reason for going back in time in the first place.  
Logically impossible (if I remember my philosophy of science right).  
You must leave things so that when time runs again (or whichever 
model one uses for time travel) when you reach the point after you 
have changed things you still decide to go back in time.
