To achieve the maximum learning effect for you, we have based our materials on original exam questions, reworked them, and provided them with detailed commented solution proposals. These allow you to check your own results and performance, and they offer clearer and more comprehensible solution paths than the bullet-point solution schemes available in the original IHK exams for the examiners, making them easier to understand for those who are not yet fully confident. The point distribution used, as in the actual IHK exam, gives you the key to a realistic grading system.
