its called "exam smart"
It's Russian roulette. Either you score high marks if your
chosen topics come out, or you get screwed if they don't.
That is to say, chance plays a high factor in what you're doing.
Heads, you win big. Tails, you lose big. That doesn't involve a lot
of smarts at all, methinks.
And at the end of the day.... 'Exam smart' is not the same as
being truly educated.
I sure hope that someday you'll understand.
