If you want to do well on the leaderboard, you'll need to answer as many questions as you can correctly. If you can answer several questions correctly in a row, your score will increase dramatically!
Don't forget that your overall time makes a difference; go slowly at first and read the information - you'll then be able to answer the questions correctly and move through the levels as quickly as you can. The answers are placed in a different order each time, so the game will reward players who have taken the time to absorb the information.
