Within ZH1 and ZH2, railway and highway parts will be written, and they will be graded separately. If both results pass then the grade is the mathematical average of the two parts. If one or both of the railway and/or highway parts fail(s) then the grade of the ZH is fail. If either or both of the parts receive less than 50% of the total score, that part of test fails.
If the examinee receives at least 50% of the total score, the exam passes. If less than 50% is achieved then the exam is failed.

3.6 Javítás és pótlás
  1. The two summative academic performance evaluations during the performance period – for the first time – can be replaced or repaired free of charge. In the case of a correction, the student from the previous result and the new result is considered more favorable for him/her.
  2. If the student does not get a grade other than insufficient even with the replacement according to point 1). to obtain, in addition to paying the fee specified in the regulations, for the second time, combined in the form of a repeated attempt to repair only one unsuccessful first restoration. Both ZH in this form cannot be replaced. The second replacement option can only be used if the person to be replaced is on ZH the Student appeared on the corresponding first replacement.
