The costs for a 21+ admission test are EUR 150. For this amount, you can take one admission test and one resit. The correct payment details are mailed to you after you complete step 2 of the application process.
If you qualify for a resit, keep in mind that it is always held during the next test window. This may mean you will not be able to start during your preferred intake window.
Note: when you apply for the test window in July/August 2018 and you fail the test, you will not be able to start your degree programme in September 2018. In that case, you can take the resit for the 21+ admission test in October 2018, which means you cannot start your degree programme until one year later if it has no multiple start dates.
