Further on evaluation

The final evaluation will be based on a written examination (counting 70%) and the project work (counting 30%) based on % fulfillment. Final grading will be from A to F. Both the written exam and project must be passed to receive a grade in the course. If you fail one of the parts, this must be re-taken to pass the course.

Permitted examination aids, support material code C: Specified printed and hand-written support material is allowed. A specific basic calculator is allowed. In addition, calculator Casio fx-991EX and fx-991CW are allowed.

Re-sit

For the written exam there will be a re-sit examination in August. For the re-sit exam, the examination form may change from written to oral. If you wish to re-take the project, this must be done the next time the course is given.
