Passing Grades: I recommend
Exceeds Expectations (E)
Failing Grades: I don't recommend
I kind of like this new rating system since I'm in love with the Potter series. And there's more choices to use. Hopefully I won't have to give a D or a T to anyone. So to give grades to the previous 3 novels I reviewed, I would have to give all three an O for Outstanding.
Don't worry you guys will see other grades around in reviews not just O's =D but, until then.
