II. Tárgykövetelmények
1, The assessment of the learning outcomes detailed in Chapter 2.2. is based on two mid-term tests, the active participation in the practical exercises (partial assessment) and on one final exam.
| Evaluation form | Abbreviation | Assessed learning outcomes |
| 1st mid-term test | MT1 | A.1 - A.3; B.1 - B.4. |
| 2nd mid-term test | MT2 | A.4 - A.6; B.5 - B.6. |
| Written final exam | Exam | A.1 - A.7; B.1 - B.7; |
A szorgalmi időszakban tartott értékelések pontos idejét, a házi feladatok ki- és beadási határidejét a "Részletes féléves ütemterv" tartalmazza, mely elérhető a tárgy honlapján.
| Abbreviation | Score |
| MT1 | 15% |
| MT2 | 15% |
| Teaching period total | 30% |
| Exam | 70% |
| Sum | 100% |
Mid-term tests and the final exam are unsuccessful if they do not achieve 50% of the available marks.
An examination result below 50% of the available marks will result in a Fail mark.To obtain a signature, 50% of the
total number of points must be obtained during the teaching period according to
point 3.3.
Mid-term results obtained in previously
semesters of the subject can be taken into account up to three (3) semesters for
the determination of final mark of the the exam.
| 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% |
1. By its nature, active participation cannot be replaced, corrected or otherwise replaced or substituted in any other way.
2. The two mid-term tests may be replaced or corrected free of charge for the first time. In the case of correction, the new result and the previous result shall be taken into account as the one which is more favourable to the student.
3. If the student fails the test according to a retake detailed in Paragraph 2, he or she can take a second attempt to correct the first unsuccessful substitution, subject to the payment of a fee specified in the regulations.
| Activity | Hours/semester |
| Participation at contact hours | 14×2 = 28 |
| Preparation for the contact hours | 14×1 = 14 |
| Preparation for the mid-term tests | 2×6+2×3 = 18 |
| Preparation for the exam | 30 |
