There is a new combinatorics e-learning framework available at www.gm.fh-koeln.de/kombinatorik/en. This tool allows you to strenghen your combinatorics competence with a set of quiz questions. The combinatorics framework was developed by a student group under my supervision. We made a German and an English version, to facilitate the use of this e-learning framework for our foreign students. Thanks go to Lukas Syla, who made this nice feature with the flag buttons allowing a fast switch between English and German content!
