Way of continuous check of knowledge in the course of semester
Verification of study:
Checktests TEST no. 1, TEST no. 2 (s. exercises)
Conditions for credit:
100% practical instruction participation. Extraordinary substitute just on the base of previous teacher acceptance.
Delivering of practical instruction course works on schedule = 1 week after appropriate practical instruction
100% check tests participation on schedule (exact date will notice minimal 1 week before). It´s possible to repeat each check test one time. In case of repeating check test it´s possible to obtain just 80% of conventional maximal amount of points!
Minimal amount of received points is 25 from 40 points.
Points classification of practical instructions - maximal 40 points, divided to:
T1 = max. 10 points
T2 = max. 10 points
Course works of practice instructions = max. 20 points
