Save the exact university page or written course-office reply that confirms the alternative evidence is accepted. General statements from unofficial websites, social media, or another university are not enough for a course-specific application.
Check whether an alternative certificate has conditions. A university may require a specific wording, a degree taught fully in English, a recent graduation date, an original letter from the registrar, or a separate approval step. If any condition is unclear, plan for an accepted test instead of assuming an exemption.
When applying to two courses, complete this check twice. An accepted alternative for one university may not be accepted by the second course, even within the same Helmut-Schmidt Programme cycle.
