If you would like to purchase a discounted public transport ticket as a Catalyst student, you are entitled to the Schüler und Azubi ticket! 

You are entitled to a 57 EUR per month or 534 EUR per year ticket. 

To buy one, bring the following to a BVG office: 

- Your Catalyst enrolment Letter (sent the first week of term to your Catalyst email address) 
- Your Catalyst student card 
- A passport picture 
- Your passport

In addition, the BVG will also issue you a Trägerkarte. This is a small card confirming your student status. You will always need to present your Trägerkarte alongside your Azubi ticket.
