The goal of the Preparatory Mathematics Course is to help first semester students at TUHH in their studies by reviewing and applying basic mathematical concepts. This course is aimed at Computer Science, Data Science and Engineering Science students as well as anyone else who would like to brush up on his or her knowledge in mathematics. It is held as an English alternative to the German "Mathematik Brückenkurs" and it runs in parallel and with the same schedule. The course consists of lectures in the morning and exercises in the afternoon to practice the covered material.
