II. Subject requirements

Assessment and evaluation of the learning outcomes
3.1 General rules
  • Evaluation of learning outcomes described in Section 2.2. is based on two mid-term written checks, the completion of two compulsory homeworks, and the solution and evaluation of two computer laboratory tasks.
  • The duration of each mid-term test is 75 minutes, the duration of each laboratory tasks is 45 minutes.
  • Compulsory homework must be submitted by the deadline specified in the "Detailed semester schedule" after at least one consultation, in a minimum of 95% completion level.
  • The dates of checks and the deadlines of homeworks can be found in the "Detailed semester schedule" on the website of the subject.
3.2 Assessment methods

3.3 Evaluation system
3.4 Requirements and validity of signature
There is no signature from the subject.
3.5 Grading system
  • In the case of complying with the requirements on attendance, the results are determined as follows.
  • Mid-term tests below 40% are regarded as unsuccessful, and two successful mid-term tests are required for the completion of the semester.
  • No requirements are made on the successfulness of the laboratory tasks.
  • Homeworks are to be submitted following at least one consultation at a 95% completion level or higher by the deadline given by the detailed semester schedule. Uploading the assignment does not mean its acceptance yet, erroneous assignments worth zero points.
  • Beyond the above requirements, the weighted average of the results must be above 50% for a passing grade.
  • The semester result is computed by the weighted average A of the best two mid-term tests, the homeworks, and the laboratory tasks as in section 3.3.:
GradePoints (A)
excellent (5)86%≤A
good (4)74%≤A<86%
satisfactory (3)62%≤A<74%
passed (2)50%≤A<62%
failed (1)A<50%
3.6 Retake and repeat
  • Laboratory tasks cannot be retaken in this subject.
  • Each mid-term test can be retaken once in this subject. The result of the retake overwrites the earlier result.
  • Online retake of the mid-term tests must be validated through an oral report.
  • Homeworks not submitted by the deadline can be submitted after paying a fee until the end of the next week after the deadline.
  • There is no second retake in this subject.
