You are strongly advised not to learn "original tasks" by heart that you have, for example, heard from people who have already taken the suitability test. This is because the DLR constantly changes the tasks.

This training software follows another principle. The number values in the text tasks are all random generated according to the level of difficulty set. Therefore you will learn by practice how to solve the types of task. Independent from the concrete numbers you will know how the given numbers should be calculated together to reach the right result.
