2.6 Egyéb tudnivalók
- Attendance to lectures is compulsory. The signature and credits from the subject will be refused to students missing more than 4 (i.e. attending less 9 classes).
- Students are evaluated based on their actual individual performance. Students are required to show evidence of their own knowledge and skills. Submitting a work of others, obtaining or giving unauthorized help (e.g. during an exam or test) cheating and plagiarism in any form is unacceptable. Whoever violate the respective Regulations of the University will be given a failing grade (1), without the possibility of retake and repeat, and will be reported to the Dean’s Office.

II. Tárgykövetelmények
3. A tanulmányi teljesítmény ellenőrzése és értékelése
3.1 Általános szabályok
The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via tests, homework assignments and class work.
3.2 Teljesítményértékelési módszerek
| Evaluation form | Abbreviation | Assessed learning outcomes |
| 1. control test | ED1 | A.1-A.5; B.1-B.7; C.3-C.4; D.1 |
| 2. control test | ED2 | A.6-A.9; B.8-B.9; C.3-C.4; D.1 |
| 1. homework | HF1 | A.1-A.4; B.3-B.5; C.1-C.2; D.2-D.3 |
| 2. homework | HF2 | A.1-A.9; B.1-B.9; C.1-C.2; D.2-D.3 |
| attendance and activity | A | A.1-A.9; B.1-B.9; C.1-C.2; D.1-D.3 |
| written examination | V | A.1-A.9; B.1-B.9; C.3-C.4; D.1 |
A szorgalmi időszakban tartott értékelések pontos idejét, a házi feladatok ki- és beadási határidejét a "Részletes féléves ütemterv" tartalmazza, mely elérhető a tárgy honlapján.
3.3 Teljesítményértékelések részaránya a minősítésben
| Abbreviation | Score |
| ED1 | 10% |
| ED2 | 10% |
| HF1 | 10% |
| HF2 | 10% |
| A | |
| Total achievable during the semester | 40% |
| V | 60% |
| Sum | 100% |
Exam score less than 50% of the available score per exam question separately and together it results in a scoreless exam.
3.4 Az aláírás megszerzésének feltétele, az aláírás érvényessége
The condition for obtaining the signature is that the score (based on 3.3) that can be obtained during the semester period (excluding exam period) according to achieve at least 50% of the points: both for each individual performance appraisal and for the cumulative in terms of score. In addition, attendance at 70% of the lectures is compulsory.
3.5 Érdemjegy megállapítása
| Grade | Points (P) |
| excellent (5) | 87.5%<=P |
| good (4) | 75%<=P<87.5% |
| satisfactory (3) | 62.5%<=P<75% |
| passed (2) | 50%<=P<62.5% |
| failed (1) | P<50% |
Control tests (ED1 and ED2) and homeworks (HF1 and HF2) are successful if the student has individually reached the 50% of the total score.
Completion of active participation is not obligatory, however, the semester grade is specified in Section 3.3. according to point weighted.
A semester is successful if the student has achieved at least the 50% of all the scores available in the semester, i.e. (ED1 + ED2 + HF1 + HF2 + A) × 50%.
In the written exam, several questions must be answered, each exam question must be answered separately and they have to reach the min. 50% of their score.
3.6 Javítás és pótlás
- Homework – in addition to paying the fee specified in the regulations – is delayed in the “Detailed semester schedule”.
- Due to its nature, active participation cannot be replaced or improved.
- The control tests (ED1 and ED2) can be replaced or improved for the first time (the date is according to the "Detailed semester schedule") free of charge. In case of correction (improvement), the new result overwrites the previous result in all cases.
- If the student is not able to obtain a grade other than insufficient (scoreless) even with the replacement according to point 3), so – in addition to paying the fee specified in the regulations – a second, repeated attempt can do to improve the first replacement of one of the failed control test in the 'replacement week'.
