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 and a test about the theoretical part. The written part contains exercises, and that could contains also basilar theoretic questions. In order to sustain the written test the student must register through AlmaEsami [https://almaesami.unibo.it/]. During this written exam the student cannot use books or notes. Electronic devices of any kind are also forbidden.
If this written test is passed, the student can sit for the test concerning the theoretical aspects of the course.
Access to the test concerning the theoretical aspects of the course is allowed only to the students passing the written part. This part of the exam dwells upon the comprehension of the relevant concepts and on the knowledge of definitions and the statements of fundamental theorems. Proofs of some theorems, may be required. The theoretical part of the exam must be passed in the same session of the written part. Only in the period january  february the oral part may be passed in the subsequent session.
