Here is the official webpage and we also maintain a less official but more practical webpage.
I have written a Student Guide and made a Poster that brings together much relevant information on the master.

To get an impression about the theses that are written at the end of our master we have:
Thesis publication series of the Master in Pure and Applied Logic
Instructions on how to submit your thesis can be found here.
