Very helpful! Especially the test section. Solely prepared with this app and passed successfully.
However, be prepared: questions and look of the actual test are different! English in actual test is much worse than in this app.
You really have to learn and prepare! Unfortunately no way around it! :-)
Last tip: use the English version in the test and solely prepare with this. All other versions are more confusing!
