Subject fundamentals
This course represents a bridge between high school and college ways of teaching and learning.
The main goal of the course is to provide the students with tools to understand and elaborate logical arguments, from simple to more elaborate ones, and to introduce the elements of differential and integral calculus for functions of one variable with applications to ordinary differential equations of the first order and of the second order linear case. Complex numbers will also be introduced and applied to the solutions of linear equations of the second order with constant coefficients. 
Expected learning outcomes
Ability to follow a chain of logical arguments. Essentials of differential and integral calculus for functions of one variable. Computational ability.

Prerequisites / Assumed knowledge
Numbers, equations and inequalities, analytical geometry and trigonometry. First properties of elementary functions.

Delivery modes
Both lessons and exercise classes will be given.

Assessment and grading criteria
The exam consists of a test and of a written and an oral part. The test (on computer, one hour long) consists of 20 multiplechoice questions of both theoretical and practical type. The students who have passed the test, can decide either to conclude the exam with only that part or they can take also a written part containing exercises and theory. In case this is passed, an oral exam will follow, upon the request of the student or of the teacher.
