Mathematical Logic

SS 2021

The lecture will be held in German. You may write your answers to the exercises and the exam in English. Please note that the German version of this page takes precedence over the information on this page.


  • Admission to exam: 220 points are required for exam admission.

    Please check the MaLo-Portal and verify that your points have been entered correctly. You should also be able to see if you are admitted to the exam or not. Exam admissions from previous years do not count for this semester.

  • We have published the exercises on this web page. Please note that you are not allowed to publish the course materials anywhere else.

  • Exam registration: Please do not forget to register for the exam via RWTHonline (first exam date or second exam date). Note that each exam registration has a deadline.

  • This course is held via the Moodle course page. Your points (and later, your exam results) are displayed to you in the MaLo-Portal. If you encounter any problems, please send an e-mail to Lovro Mrkonjić.

The MaLo-Portal displays your current points and preliminary exam results, if available.

Course Material

The current course material is available on the Moodle course page. Note that the preliminary material on this page will not be updated during the semester.




Please refer to the Moodle course page or RWTHonline for current information about the exam and dates or visit the German version of this page.
