The grades I give in these posts are :

A+ is the highest 'grade', followed by : A (straight A),
A-,B+,B,B-,and C which is for average.
These are my impressions of the performance on stage

Croatia - straight A ,
Ireland - C much better than a turkey!,
Latvia - C ,
Serbia - B interesting piece.
Poland - C ,
Norway - A- ,
Cyprus - B (loved the singer),
Slovakia - C ,
Denmark - C (great song),
Slovenia - B ,

Azerbaijan - B- ,
Greece - C (not a good performance today),
Lithuania - A- ,

Albania - A+ ,
Ukraine - A+( unbelievable),
Estonia - A (loved the singer),
Netherlands - B- .
we all have our favorites,and i noticed a trend in my
favorites-each year, I like: Estonia,Cyprus,Portugal,and Turkey.
Only Cyprus didn't make the 2009 final.
