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 theoretical component is 6 marks.
- The minimum grade of the practical component is 10 marks.

Calculation formula of final grade

Final grade of the course:
NF = 0.25*P + 0.75*(0.3*NT + 0.7*NP)
Where,
NF – Final grade of the course
P - Project grade
NT – Test grade
NP - Practical component

Practical component is obtained as follows:

NP=0.5*REL+0.5*AC
where
REL - weighed grade of two reports of the practical assignments made, respectively REL1 and REL2, one at the Chemical Department laboratory, another at the MIning Department or Metallurgical and Materials Department laboratories; REL =0.5*REL1+0.5*REL2
and
AC – continuous evaluation component, a personal opinion obtained by analysing student behaviour in the lab, looking at its notebook, evaluating answers to some questions ...

Examinations or Special Assignments

The final grade of the course includes the evaluation of the following components:

Theoretical component: one 50 minute written test, with no consultation, on the contents related to the practical assignments done in all the three laboratories. The specific questions asked will be proportional to the weight of each module (or Laboratory) in the total practical assignments. It will have a classification (NT).
Practical component: Continuous evaluation of practical classes (AC) and two complete reports per group (REL); The page limit is 10.
AC – 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 evaluated in each class, as well as the laboratory performance, which will function as a support to the attribution of the continuous evaluation grade (AC). As an alternative for the laboratory exercise book evaluation, the teachers can choose to demand the presentation of a short report (2 A4 pages maximum) on the seven days after the assignment is done.
REL – One of the reports will be obligatorily on the Chemistry Laboratory module (REL1) and the other will be picked out from the other two modules (REL2)
All the classifications will range 0-20.

Special assessment (TE, DA, ...)

Not applicable, since it is not expected that special students frequent this subject.

Classification improvement

The theoretical component is the only grade which can be improved. This will be done with an exam in the re-sit examination period.

Observations

All the laboratorial procedures to be used at the practical sessions in the laboratories will be loadable at the site of CER in the SiFEUP in the format of either .doc or .pdf files.
