Hello Do Khoi!
As far as I know, there are no real entrance exams in order to start with the International Business programme. All information on requirements can be found under the following link: https://www.saxion.edu/programmes/bachelor/international-business/toelating. In case you have any questions about those requirements, you can contact the international office (internationaloffice@saxion.nl ).
I hope this helps at least a little bit. If not, feel free to reach out to us again!
