The subject Chemical Reactivity consists of two types of supervised activities, theoretical lessons and problem classes, which are distributed throughout the course.

Theoretical lessons.
Through the teacher's presentations, the student must acquire the specific knowledge of this subject and complement it with the study of each topic treated with the help of the material that the teachers can provide to the student through of the Virtual campus and the recommended bibliography. The theoretical lessons will be open to the participation of the students, who will be able to ask the teacher the questions and clarifications they consider necessary.

Exercises lessons.
The aim of this supervised activity is to solve problems and questions that have previously been posed to the students through the Virtual Campus and that they have previously had to solve, in groups or individually Due to the reduced number of students in class during this activity, the aim is to stimulate students' participation in the discussion of alternatives to solve the problems, taking advantage of this to consolidate the knowledge acquired at the theory lessons and during the autonomous work.

CONTINUOUS ASSESSMENT:

The final grade for the course is obtained from the exam scores, the student's continued work (evidence of learning), and laboratory practices.

Final course grade = 0.10 x (continuous work grade) + 0.70 x (average grade of the partial exams) + 0.20 x (laboratory practices grade)

To pass the course, the final grade must be ≥ 5.0 (out of 10) and the following two conditions must be met:

1) The exam score for each partial must be ≥ 4.5 (out of 10)

2) The grade for the laboratory practices must be ≥ 5.0 (out of 10)

Students who fail the course due to not meeting either of the two conditions above, regardless of whether their final grade is greater than or equal to 5.0, will receive a maximum final grade of 4.5, and the course will be considered failed.

Continuous work (10%):

1) Evidence will be collected from each student throughout the semester (problems solved individually or in groups, self-assessments on the virtual campus, short tests in class, quizzes, etc.).

2) The grade for the continued work will be the average of the grades for the evidence collected throughout the course. Failure to attend an evidence session results in a zero for that evidence.

Class attendance will be factored into the final grade, as per the instructors' guidelines.

Exams (70%):

1) An exam will be held at the end of each part of the subject(1st partial exam and 2nd partial exam).

2) Retake exams will be offered for both parts of the course (second-choice exams). To participate in retake exams, students must have previously been assessed on a set of activities worth at least two-thirds of the total course grade. Students who do not require retake exams may perform the retake exams to improve their course grade.

- For students taking these second-choice (make-up) exams, the grade for the block exam will be the one they obtain in this second-choice exam.

- For students taking these second-choice exams (grade improvement), the block exam grade will be:

• equal to that of the second-choice exam, if the second-choice exam score > the midterm exam score
• equal to the average of the partial exam and the second-choice exam, if the second-choice exam score < the partial exam score.

Practices (20%):

The final grade of the laboratory practices will be calculated from the lab reports.

If the subject is failed, but the laboratory grade is higher than 6.0, it will not be mandatory to repeat the laboratory practices in the following year and the laboratory grade will be maintained, provided that 75% of the same practices are maintained as the previous year in which the subject was failed.

Anyone involved in an incident that could have serious safety consequences may be removed from the laboratory and fail the course.

SINGLE ASSESSMENT:

Within the regulatory period established by the University, students may request the single assessment, waiving the continuous assessment option. Students who opt for this single assessment option must take a final exam consisting of an exam covering the entire theoretical syllabus and problems from the course. This exam will have two subtests corresponding to the sections of the course (equivalenttothe first and second partial exams, respectively) and will be held on the day the continuous assessment studentstake the second partial exam. The student's grade will be:

Final course grade = 0.80 x (average grade of the final exam blocks of the subject) + 0.20 x (laboratory practices grade)

To pass the course, the final grade must be ≥ 5.0 (out of 10) and the following two conditions must be met:

1) The exam score for each block must be ≥ 4.5 (out of 10)

2) The grade for the laboratory practices grade must be ≥ 5.0 (out of 10)

If the final course grade does not reach 5.0, students may take a second-option exam for the entire course. This exam will also consist of two tests from the theory sections, and the same passing requirements will apply (a minimum of 4.5 in each section). This second-option exam will coincide with the retake exam date for students who opt for continuous assessment.

RATING OF "NOT ASSESSED":

The rating of "NOT ASSESSED" will be obtained in the following cases:

• There is no grade for laboratory practices (attendance at practical classes is mandatory).
• When the student has not participated in any of the assessment activities of one of the partial exams into which the subject is divided (exams and continuous work).

OTHER:

The commission of any irregularity in an assessment act (academic fraud, plagiarism or improper use of AI, unless this use is expressly authorized in the teaching guide), which may lead to a significant variation in the grade, means that this act will be graded with a 0. In the event that the teaching guide provides that in order to pass the subject it is an essential requirement to have obtained a minimum grade in this assessment act or that several irregularities occur in the assessment acts of the same subject, the final grade for this subject is 0. Apart from this, a disciplinary process may be initiated against the student who incurs any of these irregularities.

To attend any exam, you must bring a valid photo ID (national ID or university card) with a recent, high-quality photograph.

In this course, the use of Artificial Intelligence (AI) technologies is not permitted at any stage, except as a study aid (always maintaining a critical perspective on the accuracy of the information provided by the AI). Any assessment activity (assignments or exams/quizzes) that includes AI-generated content or shows signs of such activity will be considered academic dishonesty and may result in a partial or full deduction from the grade, or more severe penalties in serious cases.
