- One written test and oral exam at the end of its course. Written test:
duration: two hours, to be made at the end of the course.
type: it consists in performing three physical exercises, at each exercise is assigned a score that contributes to the final mark.
objectives: it aims to ensure the ability to use the fundamental concepts and the applications of them to physical systems and solving problems.
oral examination
duration: up to 1 hour.
type: it consists primarily in the discussion of the written test, with the request to depth of its theory.
objectives: evaluate the level of knowledge and mastery of basic concepts and application to problems in Physics. - Extended program
