2 more finals

Haven't been writing so many month, and suddenly this posting.
Well, usually people are studying harder during the finanl exam week.
It does not applicable to me. I don't know why I don't study as hard as regular semester week, but I think one reason would be when I was young my grandpa told me if you are really smart, you don't study during the final exam week.
In a way, this is true. since there is no more additional subject (topic) to cover for the exam, at that point, I should know all the material and must be able to answer the all questions of a final exam.
But this statement is true with the premises of I study hard during the regualr semester.
