General clarifications on instruments for evaluation:

The evaluation of this subject consists of three parts:

1. THEORETICAL CONTENTS: They will be evaluated by a written exam consisting of 20 short questions. The aim of this exam is to check the

knowledge of students about the contents explained in lessons 1-8. The weighting of this part represents 70% of the global mark.

2. SEMINARS. The exam will consist of 1-2 practical questions. The aim of this exam is to check the ability of the student to solve practical problems

related to the use of separation techniques in quantitative chemical analysis. The weighting of this part represents 20% of the global mark.

3. LAB PRACTICES. The exam will consists of 6 questions on the methods and contents involved in the 3 lab practices that will be developed. The

weighting of lab practices is 10% of the global mark (5% for the exam and 5% for student attendance to the lab practices).

RULES TO PASS THE SUBJECT

A mark representing the 50% of each evaluation part (i.e. Theoretical contents, Seminars and Lab Practices) will be required to pass the subject.

Student attendance to lab practices is mandatory to pass this part.

Marks above 50% corresponding to Lab Practices and Seminars will be kept until passing the Theoretical Contents.

Clarifications on the methodology for part-time students and students with disabilities and special educational needs:

Evaluation and methodological adaptation for part-time students will be carried out according the general rules established by the Faculty of

Science. The methodologies will be adapted to the difficulties faced by students with any disability.

Qualifying criteria for obtaining honors: Conforme la artículo 49c del Reglamento de régimen académico. Para calificaciones finales similares,

prevalecerá la mayor puntuación en el examen final de la asignatura


TEACHING GUIDE




General clarifications on the partial evaluations:

Se realizará un examen parcial referente al contenido de las lecciones 1-4. Se requerirá una nota mínima de 5 para eliminar la materia en el examen

final.
