Learning objectives
The aim of the curse is twofold. First, to provide students with a basic mathematical language, allowing them to formulate a problem in a correct way and to understand a problem formulated by other people. Secondly, to provide the necessary instruments to solve some specific problems, ranging from the behaviour of sequences to that of series and functions of a single variable.
Expected learning outcomes
Students have to correctly express a selected number of basic mathematical notions and instruments. Moreover, they must know which instrument is the most suitable to solve
some classical problem in Mathematical Analysis. Finally, they must be able to use such instrument to solve the problem itself, or at least have the appropriate know-how to understand some helpful mathematical text.

Assessment methods and Criteria
The exam consists of a written test and an oral test in the same exam session..

The written test lasts 2 hours and consists of two distinct parts:
Part 1: The student will have to answer some simple questions indicating only the result.
Part 2: The student will have to solve some exercises on the topics covered during the lessons, indicating for some exercises only the answer, for others the procedure and the answer. The student will also have to answer some theoretical questions related to the program (definitions, statements of theorems, proofs of theorems).
In addition to the answers, the procedure to solve the exercises and the correctness of the demonstrations will be taken into account.
Passing Part 1 is a necessary condition for the correction of Part 2 (i.e. if Part 1 is not passed, the test is insufficient and Part 2 is not corrected). The final mark is determined only by the mark of Part 2. The written test is passed if the mark is greater than or equal to 18/30.

During the exam the student cannot consult notes or books, nor use calculators or other calculation tools.

The written tests will be held in the 5 exam sessions distributed in the months of January, February, June, July, September.

The written test can be replaced by two "in itinere" tests reserved for freshmen only (matricole). The first in itinere test will take place in November, the second immediately after the end of the lessons in January.
The structure and rules of the in itinere tests are the same as those of the written tests, except that they last 1 hour and 30 minutes. To pass the written part with the in itinere tests it is necessary to obtain at least 16/30 in each test with an average of at least 18/30. The final mark of the written part will be the average of the two marks (rounded up).

Only freshmen (matricole) are admitted to participate in the in itinere tests. The in itinere tests will be online.

The oral exam will take place in two ways.
1) If the student wants to confirm the grade obtained in the written test, the oral test is limited to the discussion of the written or in itinere tests. In addition, the proof of one of the theorems indicated in the definitive program will be asked.
2) If the student wants to improve the grade obtained in the written test or in the in itinere tests or obtain honors, then he/she must also pass an oral test on the topic of the whole program in the same session (definitions, statements of theorems, proofs of theorems).
For the in itinere tests the oral exam will be held in January.
In case of negative evaluation of the oral test (in both modalities) the mark obtained in the written test could be modified accordingly or even the written test will have to be repeated.
In case of negative evaluation of the oral test, the mark obtained in the written test could be modified accordingly or even the written test will have to be repeated.

To participate in a written test or in an in itinere test it is necessary to register through the system provided by the university, by the deadline indicated. The candidate is required to show a personal identification document with a photograph.
