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 two midterm tests, homework assignment and written examination.

3.2 Teljesítményértékelési módszerek

Evaluation form	Abbrev.	Assessed learning outcomes
1st midterm test	MT1	A.1-A.2; B.1; C.1-C.2
2nd midterm test	MT2	A.3; B.1; C.1-C.2
homework (small homework)	HW	B.2-B.3; C.1-C.2; D.1
written examination	E	A.1-A.5

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
MT1	15%
MT2	15%
HW	20%
Total achievable during the semester	50%
E	50%
Sum	100%

3.4 Az aláírás megszerzésének feltétele, az aláírás érvényessége

To get the signature you must exceed 40% of the maximum score of both midterm tests and prepare the homework individually, without sharing with others, at a sufficiently good quality.
If you already obtained the signature in a previous semester and you join a normal (not an exam) course, then your new result will overwrite any previous result.
If you have achieved midterm results counting towards your exam grade of this subject sometime in the four previous semesters, then these results may also be accepted in the current semester.

3.5 Érdemjegy megállapítása

An exam not exceeding 40% of the maximum score results in a failed (1) exam.
If you pass the exam then the final grade is calculated as the weighted average of the midterm tests, homework and final exam as specified in Clause 3.3.

Grade	Points (P)
excellent (5)	85%<P
good (4)	70%<P<=85%
satisfactory (3)	55%<P<=70%
passed (2)	40%<P<=55%
failed (1)	P<=40%

3.6 Javítás és pótlás

Late homework can be submitted till the deadline determined in the Detailed course schedule, after paying the fees due according to the regulations.
Any of the two midterm tests can be retaken at the time and place specified in the Detailed course schedule. This first retake is free regardless of your previous score, i.e., you can also retake in order to improve the score of a passed midterm test. In any case the new score overwrites the previous.
If you cannot pass the subject (obtain a final grade higher than 1) with the retake in clause (2) then you can try to improve one failed midterm test a second time. This second retake is not free, however: you must pay the due fees according to the regulations. The time and place of the second retake is also specified in the Detailed course schedule.
