How to know the answers in advance?

Ask any student if he /she knows what is the best way to know the answer to a question in advance. He/she will tell you: by knowing the questions in advance. And it’s nothing more than that. But how can you know difficult and different questions in advance. Be the smartest kid on the block and bring out the worst in yourself, the meanest in your character, the dirtiest attack you can imagine. Think of the tough, the smart, the obvious, the unexpected questions and prepare for them. It's that simple.
