Yes. If you are missing ECTS, whether in Specialized knowledge 1 or in Selection criterion 2, you can use the time until the next application period to acquire the missing ECTS.
Acquire the missing ECTS in the winter term. Enroll in a bachelor’s programme for this purpose, e.g. in a bachelor in mathematics. Or enroll as a guest auditor or a visiting student and take courses. Please note that only courses that have been completed with an examination at a recognized higher educational institution can be recognized.
In the summer semester, you can already take basic courses from the master’s programme in statistics and have them recognized later if you have been accepted into the master’s programme in statistics.
