Additional information on implementation and assessment Type (examination, oral, coursework, project):
• Laboratory work
• Written exam
• Oral exam
Notes:To pass the exam, the student must pass each part of the exam (the written part of the exam, the oral part of the exam) with at least 50%. Two colloquiums that can replace the exam are planned, if each one is passed with at least 50%. The colloquia are valid until the end of the current academic year.
