Supervised projects |
A5 A11 A12 A15 A29 B1 B2 B3 B5 B7 |
Assessment will be based on providing correct answers, clarity of explanations and documentary sources used. The score depends on work carried out at individual (10%) and group level (10%).
|

Mixed objective/subjective test |
A5 A11 A12 A15 A29 B1 B2 B3 B7 |
The degree of general knowledge and understanding of the subject will be assessed.
Consists of two parts.
One is related to theoretical content and represents 70% of the score.
The other is related to the laboraroty practices and represents 10% of the score.

Assessment comments |
To pass the course, the score must be 5 or higher but with at least a 4 in each part of the test.
If the sum of the score of all activities is higher than 5, but the score on one part of the text is lower than 4 then the final score is 4.9 (failing score).
It is considered "NP" (non attendance) when less than 30% of the assessed activities were carried out.
Preferably, first class honors will be awarded in January among students with a score of 9 or higher.
A mid-term exam will be held. A score of 5 or higher will be maintained until July.
In July there is the opportunity to retake only the test. The January's score of supervised projects is maintained.
