How to participate ?

Registration is free and open during the entire duration of the challenge.

You will have 12 minutes to give the correct answer to as many questions as you can. The questions will be multiple-choice with one or several good answers. The on-line test contains questions with 3 levels of difficulty: Low, Medium and High with an associated score of 1, 2 or 3 points, if answered correctly. The total score will be the cumulative score of the questions. A wrong answer always gives the same negative score (-1). When you pass on a question, you don’t win or lose points.

  1. You firstly need to register on EDITx.
  2. To launch the challenge, press the button “participate”.

The quiz allows the usage of two ‘jokers’: the "50/50", forcing the on-line test to take out half of the answers and the "Ask the challengers", whereby the percentage of the challengers choosing each answer is displayed to you.

What will be displayed at the end of the challenge ?

After you completed the challenge, you will see your result for that Challenge immediately, but not the answers. We are emailing the details of the scores to all players at the end of the Challenge, so that the answers can't be shared among players during the Challenge.

Your score and the private leaderboard will be released at the end of the challenge and only visible to you.

If you are ranked in the TOP 50 participants

If you are ranked among the top 50 participants, your name, first name and score will be posted on the leaderboard and visible to all the challengers. At the end of this round there will be 16 finalists who will be invited for the Final.
