Answer randomly selected questions. Points are given for correct answers, time and difficulty.
This is how it works:
Base point equals difficulty
Time gives +50 points if answer is within 10 seconds. Point is reduced with 10 every second until a minimum value of -100 (25 s)
Base point equals reversed difficulty (if difficulty is 75 you get -25)
Time has same affect as for correct answer but you may not get point over 0 at wrong answer.
Highest score at the end of the Race wins!
