**(A) Teachers and time table.**

Teacher: prof. Fausto Gozzi;

Assistants: dr.ssa Daria Ghilli and dr. Antonio Veredice;

The course starts Monday, September 20 and ends Friday, December 3 with the following schedule:

Monday 10.45-12.15 (online room 38)

Tuesday 9-10.30 (online room 70)

Thursday 10.45-12.15 (online room 61)

Friday (face-to-face): 8-9.30.

Supplementary hour online: Wednesday 10.45-12.15. Sometimes it may be used for recovery. In such case there will be a notice in the website of the course.

The course “Lab of software application for economics” will teach you how to use some software to solve some of the mathematical problems which you will encounter in this course. The teacher of such course is Prof. Anna Maria D’Arcangelis. Information about this course can be found at the web page of such course.

**(B) Precourse, self-evaluation test and tutoring.
**

The course starts giving for granted the basic arguments (one variable calculus and basic linear algebra) taught at the standard mathematics courses of the italian “laurea triennale” in economics and similar subjects. It is our experience that some students may not remember well such topics, as in many cases they studied mathematics only the first year, while mathematics is a skill that needs to be trained frequently.

Till last year the University has provided a precourse (with a teacher) summarizing part of the basic arguments needed to be able to understand the lectures of the course. This year the precourse has not been organized (hence there is no teacher for it) but the material of the precourse of the previous year is still online and the students are invited to look at the precourse material online at this site:

https://learn.luiss.it/course/view.php?id=1814

*It is compulsory for all students to study the precourse material (unless they perfectly remember all the topics treated there). It is also compulsory to take the final self-evaluation test of the precourse. The students who get a grade strictly less than 18 in the self-evaluation test must contact TAs to agree about a recovery plan that can help them to understand the course.
*

**Office hours and forums
**

The office hours below are valid only during the course (i.e. from September 20, 2021 till December 3 2021). After the course the office hours will be only by appointment (to agree personally or by email). During the course it is always possible to ask questions after the lectures and/or request supplementary office hours by email. In some cases office hours will be advertised in the section “Hot News” at the beginning of this web page.

**Professor**: *Fausto Gozzi*. Wednesday h.8.00-9.00 (online over Microsoft Teams or other platforms). Email: fgozzi at luiss dot it).

**Assistants**.

*Daria Ghilli*: Friday 14-15. Email: daria.ghi88@gmail.com

*Antonio Veredice*: Wednesday 9-10. Email: antonio.veredice@uniroma1.it

To interact with the professor and the assistants and/or among them, the students can also use the forums which are activated on the page of this course on the luiss learn website. Every student can post and/or ask questions on the general forum. This should be the standard way to ask questions about the course. Of course, for private questions, the students should use the email.

**(F) Exams rules**

*There will be no mid term exam.*

The exam program consists of two parts: the first part (P1) concerns basic topics with some basic applications; the second (P2) concerns slightly less basic topics and some more applied models. Students can decide to take only the first part (P1) and in this case the final grade will be a maximum of 25.

There is a two-point bonus for those who, enrolled at the academic year 2021-22, take the exam within the February session.

For those who take the exam only on the first part, if the grade plus the bonus is greater than 25, the student can only register 25.

1) Students that wants to get a degree less or equal to 28 can avoid studying this part and will not receive questions about it. The degree will be at most 28 (included the bonus).

2) Students that wants to get a degree possibly more than 28 must study this part and will receive one or more questions about it. The the degree may be more than 28.

If a student does not answer correctly to at least one question of the optional part, the grade cannot be more than 28, including the bonus.

* (i) The case in which it is possible to carry out written tests face-to-face.
The student who has achieved a sufficient mark in the written test can choose to:*

*a) record the grade (without taking the oral exam);
b) take the oral exam. *

*In case a) the maximum grade that can be recorded is 25 (therefore a student with a grade higher than 25 in the written test who decides not to take the oral exam could record a maximum of 25).*

**Important note.**

*In this case the choice to register the grade without taking the oral exam must be validated by the professor. For some students the professor may decide that the oral exam is needed in any case.*

The questions proposed in the oral exam concern both theory topics and practical exercises.

A sufficient grade obtained in the written test is maintained until the last useful exam session of the current academic year and no later than that date (without any exception). Therefore, it is possible to plan any oral exam in a subsequent session with respect to the one in which the written exam was taken, as long as it relates to the same academic year.

The student has the right to refuse the grade of the written test and/or the oral test. The refusal of the grade obtained in the oral test entails the need to take the written test again in any of the subsequent sessions foreseen in the exam calendar.

*About the written test (if any).*

**The written test may include theory questions and is completely “closed-book”: it is not allowed to consult books and / or notes and the use of electronic devices of any kind is not allowed. People using any of such devices or violating rules will be carefully prosecuted.
**

**The written test can be repeated at each available date but every delivery cancels the previous grades. The oral exam (or the registration) can be done at every available date (but in the same academic year), not necessarily the same of the written exam.**

**(ii) The case when it is NOT possible to carry out written tests face-to-face.**

The exam will be oral only and will necessarily take place online.

The student must communicate whether she/he intends to carry out the oral exam on the whole program or only on the first part (P1).

In case of oral only on the first part, the maximum achievable mark will be 25.

In the event of an oral on both sides, the vote will have no restrictions (neither upwards nor downwards).

If a student takes the oral exam on the first part and refuses the grade, she will then have to repeat the exam.

The written test can be repeated at each available date but every delivery cancels the previous grades. The oral exam (or the registration) can be done at every available date (but in the same academic year), not necessarily the same of the written exam.

The oral exam cancels all the previous written/oral tests. Hence if a student does not take the vote of the oral exam she has to repeat the exam.
