Teaching methods and general organization

 

• Theoretical lectures

• Class exercises

• Laboratory exercises

• Laboratory demonstrations

• This subject is taught entirely in English 

 

 

Official assessment of learning outcomes

 

— Reports on class exercises/problems.

— Report on laboratory sessions. Attendance to all face-to-face laboratory sessions or equivalent online activities is a mandatory requirement to access the final exam and/or repeat assessment.

— Comprehensive exam in January.


Weighting

— Problems: 20%.

— Practical work: 20%.

— Final exam: 60% (35% materials, 25% biomaterials).

A minimum grade of 3.5 out of 10 is required in the final exam to apply the continuous assessment criteria. If this requirement is not met, only the grade achieved in the final exam (out of 10 points) will be considered as the final grade for the subject. 


Repeat assessment

Repeat assessment takes the form of an examination with the same content and weigh as the final exam. All students who fail continuous assessment are entitled to repeat assessment. No minimum or maximum grade is required to be entitled to take this examination. A minimum grade of 3.5 out of 10 is required in the repeat assessment exam is required to apply the continuous assessment criteria.
