Knowledge evaluation will take into account both the theoretical and the practical knowledge, and also, the abilities to use the computer for solving concrete problems. The laboratory activity consists of designing programs (as homework which is controlled by the assistants) and running them. Attention will be given to the way the students design, implement, and document their programs. At the end of term the activity is followed by an exam consisting of two parts: a written exam, and a practical one. The first one must verify the theoretical knowledge and the capacity to design and implement correct Pascal programs, and a first grade (E)is given for this. The practical examination consists in designing, testing and debugging a Pascal program, for which a second grade (P) is given.
The laboratory activity of students will be graded by a third mark (L), and the documentation written during the term will received the fourth grade (D). The final mark is the average of these four gradess, but only if they are at least 5, otherwise the exam is not given. Therefore, final grade = 50%E + 25%P+ 10%L + 15%D.
