Assignments:
The attendance of the course has certain rules: automatic assignment of F grade in case of cheating during exams and/or plagiarism, no incompletes, and no make-up exams.
All important subjects will be discussed during the lectures and visits therefore your attendance is essential.
There are two homeworks and two tests. The first written test is a theoretical test. It is scheduled on the week 11. The duration of this test is 30 minutes. The second test is a practical test about the 3D modelling. It is scheduled on the week 13. The duration of this test is 45 minutes.

Disciplinary Measures Against the Application of Unauthorized Means at Mid-Terms, Term-End Exams and Homework
The following students are subject to disciplinary measures.
(a) *Those students who apply unauthorized means (book, lecture notes, etc.), different from those listed in the course requirements and/or adopted by the lecturer in charge of the course assessment, in the written mid-term exams taken, and/or
*invite/accept any assistance of fellow students, with the exception of borrowing authorized means, will be disqualified from taking further mid-term exams in the very semester as a consequence of their action. Further to this, all of their results gained in the very semester will be void, can get no term-end signatures, and will have no access to Late Submission option. Final term-end results in courses with practical mark will automatically become Fail (1), the ones with exam requirements will be labelled
Refused Admission to Exams.
(b) *Those students whose homework verifiably proves to be of foreign extraction, or alternatively, evident results or work of a third party, are referred to as their own, will be disqualified from taking further assessment sessions in the very semester as a consequence of their action. Further to this, all of their results gained in the very semester will be void, can get no term-end signatures, and will have no access to Late Submission options. Final term-end results in courses with practical mark will automatically become Fail (1), ones with exam requirements will be labelled Refused Admission to
Exams.
(c) *Those students who apply unauthorized means (books, lecture notes, etc.), different from those listed in the course requirements and/or adopted by the lecturer in charge of the course assessment, in the written term-end exams taken, and/or
*invite/accept any assistance of fellow students, with the exception of borrowing authorized means, will immediately be disqualified from taking the term-end exam any further as a consequence of their action, and will be inhibited with an automatic Fail (1) in the exam. No further options to sit for the same exam can be accessed in the very same exam period.
(d) *Those students who alter, or make an attempt to alter the already corrected, evaluated, and distributed test or exercise/problem, i. as a consequence of their action, will be disqualified from further assessments in the respective semester. Further to this, all of their results gained in the very semester will be void, can get no termend signatures, and will have no access to Late Submission options. Final term-end results in courses with practical mark will automatically become Fail (1), the ones with exam requirements will be labelled
Refused Admission to Exams; ii. and will immediately be inhibited with an automatic Fail (1) in the exam. No further options to sit for the same exam can be accessed in the very same exam period.
Assessment, grading:
Grades will be determined as follows:
Home work 1
Home work 2
Test 1
25%
15%
30%
30%. Test 2
According to academic regulations, students may miss a maximum of 30% of the classes. After having missed 30% of the classes, the professors have the right to give the student an “F” or “1” grade.
