You will find relevant links to the partner universities if you click on one of the universities, that show under "Erasmus+ Partner Universites" and "Partner Universities Outside Erasmus+" (e.g. semester dates, courses, language requirements,...). This information will be provided gradually for all partner universities. Therefore, for some universities you will only find the link to the main page at the moment.
An overview with all partner universities can be found in this PDF document (status: July 2021).
