Learning process and workload
There are 48 course hours, 38 of which are ordinary lectures where the syllabus is covered. The remaining 10 hours will be dedicated to SAS JMP or Excel demonstrations in class.
For each week there will be given a work programme with literature references and exercises. Training / use of Excel will be integrated into teaching. In the lectures the theory will be exemplified by a set of SAS JMP data samples with exercises. The final exam is loosely based on these SAS JMP examples.
There are 8 mandatory multiple choice tests to be answered in It's Learning.
If a test is not approved in the first try, the student can retry. It is mandatory that the student get approved at least 5 of these tests in order to take the final exam.
