The course MR2 is a free study activity which you are strongly recommended to attend. During the course you are to work on your presentations of the article, the animation program and the exam topics. Furthermore, some of you should give an 8 minutes talk on one of these subjects.
MR2 is not a part of the Mathematics 2C course, but an independent 1ECTS course. It consists of 3 half day sessions. In order to pass MR2 you must be present for at least 2 of these sessions (whether you pass MR2 or not has absolutely no connection to the Mathematics 2C exam later in June).
