I have gained this software about 3 months before my MPU and could thus very well prepared for the test. Especially recommended as the test (MPU) included, are the reaction tests, the most common questions with ulterior motives and the expiration of the MPU. The similarity between test and software was impressive.
I was in the 3 months to prepare (thus is only the preparation meant by the software, not the rest) 2x a week with the software employed and passed the MPU easily. Of course, success depends on many factors but this software will help for little money more significantly.
