Laboratory measurements are 3 hours long 12
times in the semester, with one opportunity for supplement measurement
accordance with th Laboratory Regulations it is obligatory:
laboratory practice result in an individual mark (based on the answers,
activity, reports). The minimal requirement of successful semester is at least
passed mark for all measurements. The mean value of the given marks for the
laboratories gives the final mark of the subject.
Maximum two opportunities are provided in
one semester for supplement failed measurements (typically the last week before
the end of semester and the next week)
Consultation time is available on-demand
after preliminary agreement
Laboratory measurement programs are based
on measurement guides in electronic form, available on the department’s
work for lab measurements
