Under 4. Scoring: The bonus was reworded as:
The time to decode the first question (in seconds) will be recorded. The timing bonus is equal to 3 x (600 - number of seconds to decode the first question). If the team takes more than 10 minutes (600 seconds), then no bonus will be awarded. (e.g. if exactly 5 minutes are spent, the bonus is 900 points). The maximum theoretical bonus is 1799 points.
Under 5. Tie Breaker: The following tie breaker sentence was added.
If there still is a tie, the scores on the highest point problems will be used in order with the team having the least letter difference from the solutions ranked higher.
