Each semester contributes a number of “Teaching Units” (TU) and ECTS credits. The TU corresponds to one weekly teaching hour for a semester in the case of independent course teaching. The TU per course are as many as the weekly hours of teaching and tutoring plus the laboratory hours of the course that may exist. The ECTS credits are a numerical value (between 1 and 60) assigned to each course, to describe the workload required by the student to complete it.

The General Assembly of the department is responsible for the preparation of the Curriculum. The Curriculum is reviewed every April.

The Curriculum is adapted to the minimum possible number of semesters required to obtain the degree, which is determined for each degree by Presidential Decree, and issued after the opinion of the National Council of Higher Education and the Faculties.

The Curriculum includes the title, content and weekly schedule (lectures, laboratory practices etc.) of all courses (both compulsory and elective) as well as their temporal succession and dependencies (if any).

During the first four academic years, students can select to attend and be examined to up to n+3 courses offered in the specific semester (the value of n corresponds to the number of courses for the current semester, as specified in the Curriculum). The course enrollment procedure takes place through the webpage Students can also use this webpage to obtain information regarding their current grades.

In case a student has not been examined or failed in courses of the first five (5) semesters of the Curriculum, he/she must enroll, in the current semester, to all these courses, provided that they are being taught in a semester that is equivalent (fall /spring) to the current one. If the number of these courses exceeds the number n+3, the student should enroll to all the courses in the order they appear in the semesters, until the number n+3 is reached. This clause is applicable to all students who will be admitted from the academic year 2010-11 and after.

After the first four academic years, students can select, at the beginning of each semester, to attend and be examined to up to eleven (11) courses offered in this semester.
