To pass the subject two basic requirements are needed:
1.- The realization of laboratory practice is mandatory to pass the subject.

2.-Reach a minimum qualification in the laboratory practice and in each mixed test. This minimum qualification will cannot be lower than 5 (over 10). Note that the subject will not be approved (even when the overall sum exceeds 5) if one of these particular scores do not reach 5. In this case, the subject is failed and the final qualification will be 4.5.

In the first and second opportunity, the students who carried out the laboratory practice but the obtained qualification was lower than 5, will have the opportunity to, in addition to the mixed test, perform a specific test related to the laboratory practice. The score of this test will replaced the grade obtained in practice for the overall rating.

In the mixed test, do not know formulation and balancing of reactions will imply the cancellation of the corresponding exercise.

Students who do not participate on the problem solving and do not carry out the short answer questions will score 0 in these sections.

The student will obtain the qualification of No Presented when the student does not assist to the laboratory practice and neither attend to the mixed test.

In the context of "continuous evaluation" the "second opportunity" is a second opportunity of realisation of the mixed test and a specific test related to the laboratory practice. Therefore, the laboratory practice (except for students who did not get a minimum of 5), problem solving and short answer questions will keep the qualifications obtained along the course, whereas the qualification of the mixed test and a specific test related to the laboratory practice corresponding to second opportunity will substitute to those obtained in the first opportunity.

The students evaluated in the "second opportunity" only will be able to opt to Mark Honor if the maximum number of the Honors for the corresponding course has not covered in its whole in the "first opportunity".

Regarding to the next academic courses, the process of education-learning included into the evaluation, is referred to an academic course and, therefore, would go back to begin, including all the activities and procedures of evaluation that are programmed for the new course.

For students with recognition of a part-time dedication and academic exemption waiver assistance, conducting laboratory practices is mandatory and they will be provided within the flexibility to allow coordinating schedules and material and human resources. Students shall be deemed exempt from the keynote sessions while assistance will be provided to the greatest number of problem solving sessions. If they can not attend the problem solving sessions, they will make a mentored work. Therefore, these students will be evaluated by the qualifications obtained in laboratory practice (20%), in the mixed test (65%), in short answer questions (5%)and in the activities of the problem solving sessions(10%). This applies to both opportunities.
