Admission Requirements

What is the required educational background?

Students who apply for the Master of Science program must have a Bachelor (or comparable) degree in one of the following:


  • Chemistry
  • Physics
  • Mathematics
  • A related engineering field
  • Comparable specialized course and Biology/Biochemistry degree holders are encouraged to apply if they fulfill the following requirements:



Required Credits:

  • 10 CP in Mathematics
  • 8 CP in Theoretical Chemistry and/or Spectroscopic Techniques and/or Quantum Mechanics and/or equivalent topics.

Note that one CP in the European Course Transfer System (ECTS) corresponds to an estimated workload of 30 hours, where an expected workload for a year of studies is 1800 hours converted into 60 credit points. These requirements serve to ensure similar starting conditions for our future students.

A good indication that you may be successful in the iMOS program, you understand most of the terms listed below:

Mathematics: You are familiar with basic mathematical concepts like real and complex valued vector spaces, matrices and operators, basis set transformations, partial differentiation, integration over arbitrary dimensional spaces, some common types of differential equations and their solutions, and basic statistical entities like distributions, averages, data regression and hypothesis tests.

Quantum Mechanics: You are able to explain basic concepts like particle wave dualism, operators, and wave functions and know the solutions to simple quantum mechanical problems (e.g. particle in the box, harmonic oscillator, hydrogen atom).

General Physics and Spectroscopy: You are familiar with basic concepts of classical mechanics, thermodynamics/statistical mechanics (e.g. microcanonical and canonical ensembles) and have some basic knowledge on approximate solutions of the Schrödinger equation such as perturbation theory and the Born-Oppenheimer approximation. You know the difference of spectroscopic concepts like rotational spectroscopy, rovibrational IR spectroscopy of simple molecules, fluorescence and Raman-spectroscopy. Since we expect a variety of applicants, we offer a preparatory course in general mathematics (Module M) right before the start of our core program, as well as a selection of elective courses that serve to strengthen your knowledge in those fields not fully covered by your bachelor studies.

Concepts of Molecular Chemistry: The coursework also requires some prerequisite knowledge of Organic Chemistry (functional groups, reaction mechanismis, chemistry of reactive intermediates) and Physical Chemistry (thermodynamics, kinetics, theory of the chemical bond, vibrational spectroscopy). See the curriculum module details of the required courses, in particular, for more information.


What is the minimum grade for acceptance?

Grade equivalencies vary depending on where you come from and there is no absolute cut-off.

Compared to the German rating system (where 1.0 is the best and 4.0 is the lowest grade), you should have an average of at least 2.0. All foreign grades will be evaluated according to this system. Please include the grading scale your university uses in your online application, if it is not entered using the German and ECTS scales. In order to give you an idea of what your chances are for admission to the program, the following rules of thumb can be applied:

  • In GPA-ratings (maximum grade 4.0, minimum grade to pass 2.0) you need at least an average of 3.0
  • In percentage-ratings (100% maximum, minimum grade to pass 40%), you need at least 70%
  • If your degree includes ratings like “first division”, “first division with distinction” etc., you should have at least earned one of the two best ratings.


How do I know if my university will be recognized?

For Enrolment at RUB, the university may rely on the Anabin database. Perspective students can search for their institutions here . This listing is not exhaustive and others may apply. Usually, degrees/universities will be recognized if

  • The university from which you earned your degree is one of the top-ranking universities in your country
  • There are both three-year and four-year Bachelor programs offered in your home country.
  • Students from China, Vietnam, and/or Mongolia must have their foreign educational documents evaluated at their home country's German Embassy for authenticity through the Akademische Prüfstelle, APS. Please plan ahead, some deadlines are as early as February to be ready for an October program start date.


What language requirements do I need to fulfill?

The language of course instruction is English. You must provide proof that you have sound English language skills.
To be accepted to the program, at least one of the following requirements must be fulfilled:

  • Completion of your first degree program in English (this means that ALL lectures must have been held in English)
  • TOEFL: minimum score paper-based 600, computer-based 250, internet-based 100; the TOEFL score must not be older than two years and mailed to us directly from the Educational Testing Service (ETS). The Institution Code is 7657.
  • IELTS: minimum score 6.0;  the IELTS score must be mailed to us directly from ETS. Note: we do not have access to the British Council / IELTS online verification system, so please have the BC send only hardcopies to the Course Coordinator / Mailing address on the Contact Us page.
  • If you have an Abitur from a German institution / Gymnasium or completed studies at RUB, please contact the iMOS Office for more information.

German language skills are not required for admission to the program. However, some pre-knowledge of the German language will be very helpful in everyday life and it will considerably help you to socialize with other RUB students. Under 'Practical Information', you can find some options for learning German prior to your arrival. Ruhr-Universität Bochum offers free German language courses for all levels each semester.
