If I only fail one component of the BSA, and I pass everything else, will I still have to end my study programme?

According to the rules, yes, but every Board of Examiners has the right to apply the hardship clause. So, for instance, if you only miss one component from your first year, but you have successfully completed all the courses of the second year, the Board of Examiners may consider it unjust to issue you with a negative binding advice. You would then still be allowed to complete your bachelor’s programme once the hardship clause has been applied. Discuss with your study advisor how the Board of Examiners of your study programme deals with this kind of situation.
