Subject fundamentals
This course represents a bridge between high school and university.
The main goal of the course is to provide the students with tools to follow the concatenation of simple logical arguments, and to introduce the fundamentals of differential and integral calculus for functions of one variable, with applications to ordinary differential equations of the first and the second order. 
Expected learning outcomes
Ability to follow a chain of logical arguments. Knowledge of the fundamentals of differential and integral calculus for functions of one variable. Gaining an adequate ability in computation.

Prerequisites / Assumed knowledge
Numerical sets, equations and inequalities, analytic geometry and trigonometry. Elementary functions and their basic properties.

Assessment and grading criteria
The main purpose of the exam is to ascertain both the theoretical knowledge of the subject and the ability to apply theory to the solution of exercises. It consists of a multiplechoice test and a written exam, possibly followed by an oral exam. The final mark is determined by the scores of the test and the written exam and, if the oral exam takes place, its result is also taken into account.
TEST. This part of the exam, which lasts one hour and takes place in a computer lab, consists of 20 multiplechoice queries, including theoretical questions and covering all the syllabus. Books or other teaching material cannot be consulted. Each question is worth one point, and the maximum achievable score is 20. If the score is less than 12 then the exam is failed, otherwise the student proceeds with the written exam. WRITTEN EXAM. This part lasts 75 minute, and typically consists of two exercises. Of these, the former is the study of a function, while the latter is devoted to some more specific part of the syllabus and may include theoretical questions. Books or other teaching material cannot be consulted. The maximum achievable score is 13. If the score is less than 5 then the exam is failed, otherwise the final score of the exam is obtained as the sum of the scores of the test and the written part, unless an oral examination is required by the teacher (or by the student, provided that the final score is at least 18). ORAL EXAM. This part of the exam, which can be requested by the teacher or by the student as described above, mainly aims at ascertaining the theoretical knowledge of the subject, and is a further element of appraisal. In case this part of the exam takes place, its result will contribute (together with the scores of the test and the written exam) to the final exam score.
