To accessStud.IP , you need a y-number, which you will receive when you enrol via TUConnect.
What is a y-number? This is the number with which you can print at the university and also use the TU-wide W-LAN. You will also receive a name@tu-bs.de e-mail address. You should activate the e-mail address as early as possible in order to receive all information about the start of the semester etc.
In the Gauß-IT-Zentrum, the computer centre of the TU, introductory events are held regularly, especially in the first few weeks, with information on where and how to print, which free software you can get from the IT centre and how to top up your printing account.
