Way of continuous check of knowledge in the course of semester

Checking test TEST No.1, TEST No.2 (see exercise) Conditions for credit: Obligatory participation in laboratory exercises. In general 2 laboratory exercises are assessed max. 20 points. All measuring protocols delivery in right term = one week after measurement lesson Pass through 2 control tests in regular terms. Test is assessed max. 10 points, i. e. max. 20 points from tests. There will be confirmed just only 80 % of obtained points in the case of different term. One of these tests it's possible to repeat, but only with 80% of achieved points and there will be written the repeated test points! Acquirement at least of 20 point from the 40 possible.
