The class offers an introduction to logic as a tool for rational inquiry and abstract thinking, and as a foundation of computer science. Students get exposure to logical languages, learning how to understand, express, and connect concepts in this languages. Students learn how to build models and proofs of logical formulae in one or more deductive systems, both manually and interactively at the computer. They acquire the skills to understand, formulate, and assess formal arguments expressed in one or more logics, as well as the preparation to pursue further studies in artificial intelligence and theory of computing.

First round: the grade is given by 25% C1 + 25% C2 + 50% P, where C1 is the midterm exam, C2 is the final exam, and P is the average of the grades in the homeworks.
Later rounds: the grade is given by 100% E, where E is a written exam, as hard as midterm, final, and homeworks combined.
Attending all classes is crucial, however attendance or lack thereof does not determine different exam rules.
