EMerald Quiz 2022 : selection step 2

You have until March 17th 2024 (included) to take the quiz. Don’t worry if the title mentions 2022, there was an issue with the website and I couldn’t change the date.


There are 24 questions (single choices or short answers).

  • single choice questions = 1 point
  • short answer questions =2 points, more than 1 answer = 3 points
  • you don’t lose points if you skip a question or if your answer is wrong
  • if you are asked to answer in a specific unit of measurement, write the number followed by the requested unit, for example, if the answer is 78 grammes, just write 78 g
  • you can skip a question and come back to it later (once you submit the quiz, you won’t be able to go back)

You have 1h45 to answer the questions. The clock will start as soon as you click on the link “start quiz”. Make sure you have enough time ahead because you will not be able to log out and log back in. Every time you answer a question, the corresponding box becomes green so that you know which questions still need to be answered. You can skip questions and come back to them before the end of the time limit. When you are done, you will click on “quiz summary”. If all your boxes are green, you will be able to click on the link “finish quiz”. 

You must score at least 30% to be considered for the next application step.


Make sure you have a calculator, a periodic table, sheets of paper and a pen.

Good luck to you all.
