Eligibility for exams

- Laboratory classes are compulsory for all the students, including the ones under article 4, items a) and b).
The minimum grade of the practical component is 10 marks.

Calculation formula of final grade

LABORATORY COMPONENT (LC)
The grade of the laboratory component will be based on students’ performance in laboratory classes (component called Continuous Assessment, CA) and in two reports on the practical assignments. One of the reports will be on the assignments carried out at the Department of Metallurgy and Materials (REP 1) and the other on the assignments carried out at the Mining Department (REP 2).
Assessment = 0.6* (REP1 + REP2)/2 + 0.4*CA
CA – Continuous Assessment (during practical classes); it will be defined by the professor in charge;
REP – grade of the reports (REP1 and REP2).

Examinations or Special Assignments

Laboratorial component: Continuous assessment of practical classes (CA) and two individual reports (REP).
CA – The students must have a laboratory exercise book where they will do a previous preparation of the assignment, take notes (data and comments), do the calculus and present a conclusion for each assignment (the previous preparation is done at home and the rest in the laboratory). The exercise book will be assessed in each class, as well as the laboratory performance, which will function as a support to the attribution of the continuous assessment grade (CA). As an alternative for the laboratory exercise book assessment, the professors can choose to demand the presentation of a short report (2 A4 pages maximum) on the seven days after the assignment is done.
REL – reports will be obligatorily on the Metallurgy and Materials Laboratory module (REP1) and on the Mining Laboratory module (REP2)
All the classifications will range 0-20.
