Students will be evaluated in a continuous way according to their attendance to the scheduled activities, their engagement in the seminars, their discussions on the questions and exercises posed by the teacher (some of which should be delivered in advance), the laboratory practices and the mixed test. Laboratory practices are mandatory, otherwise the subject will not be aproved. At the end of the laboratory practices a report should be delivered. It should contain the analytical procedures, the experimental results and a discussion on them.

To pass the subject, a minimum score of 4 (out of ten) will be required for each activity. Then, all the scores must yield a minimum sum of 5 (out of ten). However, note that the subject will not be aproved (even when the overall sum exceeds 5) if a particular score does not reach 4. In this case, the final score of the subject will be "fail" (score = 4,5).

The "Not presented" score will be obtained in case the student makes less than 25% of the academic activities.

Note that "continuous evaluation" means that the second opportunity of July is a second opportunity for the exam (subjective test). Following, the scores of the laboratory classes, seminars, etc. obtained previously will be maintained. The score of the new exam will substitute that from the first opportunity.

For next courses, no score will be maintained and all activities will have to be repeated.

The maxixum score (10, Matricula de Honor) will be obtained by pupils doing the second exam (July) only if that score was not given in the first exam (May-June), according to the Administrative requirements.

Students being recognized officially as partial-time and/or exempted from regular attendance to the lessons, will be evaluated only according to their scores on the objective tests (85%) and the laboratory practices (15%). For them, the laboratory practices will be scheduled as flexible as possible, although taking into account the regular timetables, as well as the instrumental and human resources available. This holds for both evaluation opportunities.
