Assessment and permitted materials
You need to obtain at least half the points that can be reached (36 out of 72 grading points) to pass. Each teacher prepares a questionnaire based on 24 grading points. To pass the exam you have to reach at least 10 points in each part.
Tests are graded based on the following rukes:
63,0-72,0 points --> sehr gut
54,0-62,5 points --> gut
45,0-53,5 points --> befriedigend
36,0-44,5 points --> genügend
00,0-35,5 points --> nicht genügendDe number of points to be reached for each question varies between tests, but is always given on the papers distributed.Signing up is only allowed through uspace, as usual.Identification: Log in with your u:account in moodle and follow the sign up instructions there.Questions during the exam? There will be a professor available through BBB during the entire time.Cheating: Students will confirm by accepting the exam download that they will write the exam without the help of others. There will be a check for plagiarism (turnitin) and also a request for oral recall on the exam. This can be random or considering a cheating attempt. In case of a cheating attempt this will be documented and the exam will not be graded.If the exam is not submitted properly, the exam is negatively graded.In case of technical problems, please send a message to the person overseeing the exam.
