All students will receive the same code to gain access to the competition. When the contest link is called up, a registration form will appear, where students will independently enter their surname, first name, date of birth, etc. This way the data and results of the competition are personalised. Therefore, individual codes are not necessary and it is sufficient to send only the contest link and the school code to your students.
If you like, you can also take a look at the competition by entering the contest link in your browser and then selecting "teacher" in the registration process - then your results will not be saved.
