## Teaching methods

The course consists of lessons describing the fundamental concepts of differential and integral calculus real for real functions of one real variable. Lessons are completed with examples and counterexamples illuminating the theoretical content. Futhermore a lot of exercises are solved in the classroom.

## Assessment methods

The examination consists of a preliminary written test that lasts 3 hours and a test about the theoretical part.
The preliminary written test consists of exercises related to the arguments of the course. In order to sustain it the student must register at the test on AlmaEsami [https://almaesami.unibo.it/] . If this written test is passed, the student can sit for the test concerning the theoretical aspects of the course. In this part, the student must show to know the concepts explained during the course (in particular definitions and theorems) and to be able to connect them. The theoretical part of the exam must be passed in the same "sessione" of the preliminary written test (exercises): in the same "appello" or in the subsequent one.
