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.
If there is a re-sit examination, the examination form may change from written to oral.
In the case that the student receives an F/Fail as a final grade after both ordinary and re-sit exam, then the student must retake the course in its entirety. Submitted work that counts towards the final grade will also have to be retaken.
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 is allowed.
Recommended previous knowledge
