Immediately after booking you will receive a confirmation email from Prometric. Check your spam filter/junk mail if you do not receive it.
The exam code indicated in the confirmation email for MCQ tests and the e-tray corresponds to your second language, namely the language for the instructions in the test environment. For the case study, written test in the field and the translation tests this code also corresponds to additional information on the language of the test and the keyboard.
A booking confirmation will also be uploaded in your EPSO account within 48 hours of booking. You should print this confirmation and bring it with you to the test centre, along with proof of identity (see 'What are the instructions for sitting the computer-based tests?').
