Assessment Method

  1. Oral exam before each laboratory exercise and evaluation of the student’s performance during each laboratory exercise (5%)
  2. 13 group (per 3 or 4 people) laboratory reports delivered within the semester (10%)
  3. Written final examination of the laboratory exercises (15%)
  4. Written final examination that includes problem solving covering the entire subjects taught during lectures and tutorials (70%)

It is noted that each student must have a grade higher than 5 in each of the above assessment procedures
