If you fulfill regular admission requirements and you have completed the necessary creditable courses at the time of application you can apply for a higher study semester. For example, if you want to apply for the 2nd semester in the summer, you need 30 completed ECTS from the Statistics Master’s programme at the time of application (usually in January), in addition to the credits needed for regular admission.
