Forms of teaching and learning

The course is taught through lectures, group work, excursions and laboratory exercises.

Workload

250-300 hours

Coursework requirements - conditions for taking the exam

• Laboratory assignments with submission of reports (group work)

• Submission of 4 numbers of mandatory assignments (group work- 3-4 students) and their approval. Each assignments will have atleast 4-5 questions to be solved numerically (using calculators and related mathematical equations discussed in class).

Work requirements must be approved before the student can appear for the exam.

Examination

Individual written exam, 5 hours. 

Allowed aids: Issued formula sheet. Calculator, with empty memory, which cannot calculate symbolically or communicate wirelessly.

In the written exam, there will be mainly (80%) numerical questions to be solved using calculators and remaining (20%) based on concepts to be answered theoretically on understanding.

Grading rule A to F.

Examiners

External and internal sensor or two internal sensors.

Conditions for resit/rescheduled exams

The exam will be held early in the following semester. More information about accounts can be found here.

Course evaluation

Continuous evaluation of the teaching throughout the semester, where the method of evaluation is agreed between the teacher(s) and students. Written final evaluation of the course.
