Self-assessments to help you choose a subject

Online-Self-Assessments (OSA)

Online Self-Assessments (OSA) are tests designed to help prospective students choose a subject by providing insights to the respective subject. With an OSA, you can take as much time as you need to find out whether your expectations regarding a specific subject are realistic and whether your interests and skills match the subject requirements. In short: Find out if a subject is right for you.

No one but yourself will see your score, and your performance on the test will not influence your chances of admission or application! The OSA is a tool designed to help you identify your academic strengths and interests.

Please note: The OSA are offered in German. Only the OSA for the M.A. English Literatures and Cultures is offered in English.

New OSA portal

At the moment, we are at work updating our OSAs and gradually moving them to a new system. This is why the OSAs are currently available on different platforms. The OSAs for the subjects Geodesy and Geoinformation, Geography, Mathematics and Romance Studies are available at https://osa.zem.uni-bonn.de2.

Before they are moved to the new OSA portal, existing OSAs for many other subjects continue to be available at, of course.

Frequently asked questions

Further information about Online Self-Assessments


Why do a self-assessment?

By taking an OSA, you gain deeper insights into a given subject, its contents and requirements. The test is not about being able to answer all questions correctly! 

The detailed feedback helps you assess whether the subject at the University of Bonn is a good match for your aptitudes and interests. Keep in mind, however, that you will only get meaningful feedback if you answer the questions and problems sincerely and seriously.


What’s in the assessment?

Depending on the subject, the OSA contains different kinds of assessments:

  • You review your expectations of the subject.
  • Sample problems give you a realistic idea of what studying that subject would be like at university.
  • Some OSAs test foreign language skills that may be important when you begin your studies.
  • Based on a questionnaire, you assess your interest in the contents of a subject, for example.

Some of the questions and problems may be tricky–but don’t let that discourage you.


How do I take the self-assessment?

An OSA takes about 45 to 60 minutes to complete. Ideally, you take it on a PC, but a cell phone or tablet will work as well. We recommend creating an account before taking the test. This will allow you to interrupt the OSA and continue later where you left off. 

To get meaningful results, it is worthwhile taking the OSA in a quiet location and with sufficient time.


What's next?

The OSA cannot answer all questions; it may even give rise to new ones. To get these questions answered, you are welcome to make a personal appointment with the degree program counselors or with the Central Study Advisory and Counseling Service5 at the University of Bonn.    

Once you have decided to apply at the University of Bonn, further information on deadlines and application procedures is available under Application, Admission and Enrollment6.

After completing an OSA on the platform, you will receive a certificate confirming your OSA participation. Some universities ask for proof of applicants’ participation in an academic orientation program as a prerequisite for enrollment. The University of Bonn’s OSA certificate may satisfy this requirement–please ask at the universities in question for further information. The University of Bonn currently does not require applicants to provide proof of participation in an OSA to be eligible for enrollment.

Your data will remain absolutely confidential. Your entries will be used only for scientific purposes to further improve the OSA tool. (For more detailed information on how we process your data, see our privacy statement).
