The Fachschaftrat AnNa is the student council for the department  of science at the HBRS. We organise events for the hochschule,  but beyond that, you can purchase your lab coats, stationary, and get the old exam papers when you're in the mood for more learning.  
Additionally you can visit our office, or contact us if ever you have some burning questions about your study. 
Our public meetings take place every second Monday, from 5pm in room A062. Feel free to attend and address your concerns, or even just to come by and see what its like.
