While each topic has a suggested type, it is often possible to work on the same or similar topics also within different project types. Particularly, it is often welcome and helpful to do a master (seminar) project as a preliminary work for a follow-up master thesis.
With a Bachelor Seminar-Project you will learn for the first time to deal with a specific topic of your study program in detail and you will lay the foundation of your further scientific work. The project work will be supervised.
The main focus of a Master (Seminar) Project is to investigate a specific topic of your major or minor area of specialisation. The project work in your area of specialisation will be supervised.
With the Master Thesis you will demonstrate that you can perform scientific work under supervision. Methodology, form and content of the performed work has to fulfil the latest scientific standards.
