Two Questions about POA

I finished my re-reading of POA last night, and I noticed two 
things.  I don't know if they have been discussed before, but as I 
am not very adept at using the search function, I cannot tell.  But 
regardless, here they are:

1.  I believe Fred and George say that a tunnel on the MM that they 
had used before that once led to Hogsmeade is now caved in.  I 
immidiately thought of the Chamber of Secrets.  Maybe somehow the 
tunnels were connected.  I don't think the twins were in the 
Chamber, but they could have been connected some way...any opinions?

2.  The twins and Percy are taking their O.W.L.S and N.E.W.T's 
respectively during POA, and at the end of the book (US edition, 
paperback page 430) we find out that they have their results!  So, 
why do we have to wait all summer for Harry to find out the results 
of his OWLS during OOTP!!  Just a FLINT??  Or did the rules change, 
I wonder?

Ok, well.  Just two small things I noticed.  What does everybody 
think?
