On the examination rules and more …

The aim of the laboratory work is to build one or more experiments using the available equipments to carry out a pre-defined physics measurement.

Five criteria are used in the final evaluation of the student laboratory work:• autonomy and dynamism during the practical work (4 points)• scientific interest for the subject (4 points)• practical work logbook (2 points)• the report (6 points)• oral examination (10 minutes/team) (4 points)

The template for the article that will be distributed during the Computing Lab SHOULD NOT be modified.
