### Course Objectives

The purpose of this course is to teach the student the basic notions of calculus and linear algebra together with the basic techniques and applications that accompany them.

Assessment methods

### Detailed Description of Assessment Methods

Students are evaluated on the basis of a written exam.

The written exam can be taken in one of the two possible ways

The written exam can be taken in one of the two possible ways

- Recommended: it can be split in four partial exams (September, October, November, January). The second and fourth partials are the main ones: each one mainly contains open-answer questions and weighs for one-third of the final mark. The first and third partials are multiple-choice tests and each one weighs for one-sixth of the final mark.
- It can be taken as a single general exam mainly containing open-answer questions and covering the whole syllabus, in one of the four general sessions scheduled in the academic year (the two regular sessions in January and February, or the two make-up sessions in June and August/September). This way is mainly meant for students who have withdrawn from the four partials procedure or could not follow it.
