Yes, definitely, there is no ECTS credit limit for taking additional modules and/or additional exams. If you don’t communicate another preference at the end of your studies, our Examinations Office will automatically account the modules with the best grades for your master’s degree. The other modules and grades will only be listed in your Transcript of Records, but not in the Master’s certificate. You may also use the modules you take additionally in other module groups, according to the rule for switching modules that is explained at the bottom of your module catalog – or in the module groups M7 (Felixible Budget Faculty of Engineering) and M8 (Free Choice Uni). It is also ok if the modules you want to use to complete a certain module group exceed the ECTS requirement for the respective group. E.g. it is no problem if you use a 5 ECTS module and a 7,5 ECTS module to complete module group M7 (which only has an ECTS requirement of 10 ECTS). Please note, however, that in this case 2,5 ECTS of the module with the worse grade of the two will be lost. You cannot split up modules and use the remaining ECTS elsewhere.
