University students can start new courses with preconditions, if they are prescribed. Such preconditions are fulfilled even if one passed the required exams with grade 2 or 5. Understanding of Physics typically needs solid knowledge of Mathematics. Because the Math and Physics background of students attending the same class are usually heterogeneous, teachers can cover the necessary Mathematic details in their lectures. Inversely, students should be forced to make efforts and reach the necessary level of the course. There are multiple well-known pedagogic approaches can by implemented. Unfortunately, due to the lack of time, teachers at the University cannot apply any of them in many cases for a particular situation. This paper discusses some selected interdisciplinary approaches of Business Informatics. Enterprise Resource Planning Systems are able to give responses most commonly in real time, which would be a great opportunity in education as well. A few Physics examples are selected in the paper for demonstration purposes how external business tools and methods can support the Education.
