Assessment methods and criteria
|
Combined examination
Completion of laboratory tasks, preparation and submission of laboratory reports, final written test and independently prepared final laboratory work including basic laboratory calculations. The student is asked questions during the laboratory exercise. The answers will verify the extent to which the student is familiar with the principle of the laboratory task to be performed on the day of the laboratory exercise. If the student does not demonstrate sufficient knowledge to perform the laboratory exercise, the student may be withdrawn from the laboratory.
