You can test your newly acquired knowledge here

Instructions: Right mouse click on ”Check it.” A series of assertions will appear. Read them and consider whether they are true or not. If an assertion is true in your opinion, select it using the left mouse button in the corresponding circle. If an assertion is false, simply ignore it and continue with the next one. You may change all your decisions by clicking on the corresponding circle. Once you are finished, you can have your choices checked. You have two evaluation options:

  • Evaluation without an indication which answers are incorrect

    Click on ”Evaluation without indicating errors”. In the white area, the number of points you obtained will appear.

  • Evaluation with an indication which answers are incorrect

    Click on ”Evaluation with indicating errors”. In the white area, the number of points you obtained appears. Moreover, all incorrect answers are marked in red color.

To repeat a test once more, it is necessary to clear all the circles back to the original state. Left mouse click on ”Clear all”. If you simply want to review what you have learned, you can read only the correct assertions. In this case, click by the left mouse button on ”Check all correct answers”.
