Exercise class "Bonus without visiting classes" : is meant for those who know for sure that they will not attend the classes but want to participate in the homework bonus. Even so offering the "Bonus without visiting classes" opertunity, we strongly recomand to visit the exercise classes as the final exam will be based on both, lectures and exercise classes.

Grade boni for homework participation (Notenbonus)

For the continuous participation in the exercise classes you may achieve a grade bonus in your exam. Modalities are as following:
  • You have to be registered in TUMonline for one of the exercise classes! (See TUMonline for the deadline.) Otherwise your homework points will not be recorded.
  • If you get the mark "reasonably treated" in at least 80% of your homework, you obtain a bonus of one degree step for a passed exam, i.e. for example a 1.7 becomes a 1.3, a 2.3 becomes a 2.0, and a 3.0 becomes a 2.7.
  • A handed in solution of a homework problem gets the mark "reasonably treated", if the corrector may observe that you well treated the problem from a mathematical point of view. It is not necessary that this treatment leads to a correct solution!
  • Multiple-Choice-sheets are extra sheets and do not count for the homework bonus.
  • Exam grades, which do not suffice to pass the exam without bonus (4.3,4.7,5.0) cannot be improved from a homework bonus. The same is true for a grade of 1.0 in the exam.
  • Any obtained homework bonus is valid for both exams belonging to the course in the semester it is obtained in, but cannot be kept for the same course in later semesters.

question How does the allocation of the exercise classes work?
info As following:
  • The exercises take place almost every week, the exact data can be found under Dates of lectures/exercise classes and office hours.
  • The registration into the exersise classes has to be done via TUMonline. Mind the deadlines given in TUMonline!
  • First, there will only be the exercise classes already listed under Dates of lectures/exercise classes and office hours. In each of the classes a given maximum number of people can be registered.
  • If the number of registrations into one of the groups reaches the limit, we will try to offer an additional class at the same appointed time. If so, we will inform you under News as soon as possible
  • As long as the registration is open and there are remaining places, you can subscribe and unsubscribe into the groups as you want.
  • Multiple subscriptions are not allowed!

question Will there be a written exam?
info Yes. Some information about the exams can be found under this link. We will inform you via this web-page as soon as the schedule of the exam is fixed.

question Do I have to register for the exam?
info Yes, you have to register via TUM-Online. A "how-to" can be downloaded here (pdf)

question Which additives are allowed to be used during the exam?
info None, except writing utensils.

question Am I automatically signed up for the repetition exam if I failed the first one?
info No. You have to sign up again.

question How does the Homework system work for the exercises?
info As following:
  • You will get an exercise sheet every week within your exercises class or via this web-page (see Exercise sheets).
  • Within the classes the exercises should be discussed within groups to get first drafts of ideas for solutions.
  • At home you should carefully write down full solutions in teams of 2 to 3 students.
  • The handing-in deadline can be found at the bottom of the exercise sheet.
  • After finishing your homework you drop it in the letter box in the basement of the MI-building, marked with the name of the course.
  • Please, write your full name and the number of your exercise class on your homework.
  • The corrected homework will be returned to you in the exercise class after the next.

question What happens if I did not pick my homework in the exercise class?
info Non-picked homework will be stored in the shelves at the entrance of the M9-finger till the end of the semester. Just pick them, if neccesary.
