An admissions statement is an official document which summarizes which programme you've been admitted to, which diploma the admissions is based on and which conditions you need to fulfil before you can be enrolled as a student. As long as the conditions are not fulfilled, your offer remains conditional.
You can download your admissions statement via the Online Application Form (OLAF). In the top menu bar, go to the section called 'OFFER' and download the PDF file.
You will only be registered as a student after all of the conditions stated in your offer of admission have been met (starting from June / July). After that you will be able to download the official proof of enrolment from the Osiris student portal.
