To merge your pre-course account with your regular student account, please proceed as follows:

1. Go to https://studip.uni-goettingen.de
2. Log in with your pre-course account. Usually it has the form p_firstname_lastname. The password should have been sent to your private email address when you registered for the pre-course.
3. After login you will find a link “Studentische Nutzerkennung verwenden” at the right side of Stud.IP.
   
4. After you click on it, enter your regular student username at “Nutzerkennung” and your student password at “Passwort”, both of which you received with your student ID
   
5. Then log out
6. Now you're only using one account. All data of the pre-course account has been transferred to the regular account and you can use the eCampus portal at https://ecampus.uni-goettingen.de for all systems
