Career orientation

Career orientation
During the combined Astronomy and Mathematics bachelor’s education programme, we support you in making choices that are relevant to your future career. You will be stimulated to think about your ambitions and potential and to reflect on how to reach your goals. By actively exploring the possibilities, you enable yourself to make motivated study and career choices.

We organise various activities to help you think about questions like:

  • What are my strong skills and what skills can I still learn?

  • In which subjects do I want to specialise?

  • What subject will I choose for my Bachelor Research Project?

  • Which electives fit my future ambitions?

  • What do I want to learn next to my studies?

  • Which master's programme will I choose after my Astronomy bachelor's and why?

  • Which type of job would I like to do in the future?
