<p>@feuxfollets: In Grade 8, I studied really hard for AIME. On the exam, I could only solve 8 questions, but I guessed an answer for a question and it was right.
In Grade 9, I didn’t study that hard, and I wasn’t that lucky, so I got a 5.
I actually felt that the questions in 2007 were harder than the ones in 2006.</p>
