The first days and weeks at the University
No fear of math
Even before classes start, you can brush up your math skills in the so-called "math preparatory course." Participation in the prep course is voluntary. The course repeats selected material from school mathematics. Mathematics is an important method in economics in order to represent processes and relationships accurately and correctly, and therefore an important foundation for your studies. You do not need to have taken math as an advanced placement class in school, but should have an interest in numbers and an aptitude for analytical thinking.
The orientation week
The first week of classes is your orientation week. On the first day of lectures you will be divided into small groups that are supported by advanced students. In numerous information sessions and the first lecture you will get to know your fellow students and create your schedule. In addition, you will take a tour of the library, have breakfast with lecturers of the Faculty, explore Göttingen on a city rally and will celebrate your first student party.
