In contrast to a first degree, a second degree means you have already completed a full programme of study at the same level (Bachelor’s or Master’s).
A second degree (in Germany) thus refers to a degree programme that someone studies for after having completed a first degree. You can study for a second Bachelor’s degree (provided you have previously completed a Bachelor’s programme) or for a second Master’s degree (provided you have previously completed a Master’s programme).
When is a degree programme “completed”?
A degree programme is deemed to have been successfully completed when all examinations required under the examination regulations have been passed, including the final dissertation/thesis. For the Bachelor’s degree this usually requires the acquisition of 180 ECTS, while for the Master’s degree it usually requires 120 ECTS.
