It doesn't really effect the plot...but could someone (English 
reader?) explain to me the prefect system?  I'm not sure that we use 
it in the US, at least, we don't use it in the public school system I 
attended.  When Percy was in 5th year, he was named a prefect.  When 
Ron and Hermione were in 5th year, they were named prefects.  I 
thought it was a one-year post.  When the trio entered 6th year, I 
assumed that other 5th years would take over...but R/H remained 
prefects.  Are there three years worth of prefects (5th years, 6th 
years and 7th years)?  That seems like alot of chiefs for not alot of 
Indians.
