Practical preparation for BZF I, BZF II, BZF E, and ICAO Language Proficiency

Theory alone does not prepare you for a radio exchange

Knowing the phraseology and being able to communicate it two different skills.

Speaking takes repetition

Question banks and vocabulary lists teach the rules. The practical part also requires you to hear, process, and read back instructions correctly.

Practice between lessons

Instructor-led training remains important, but it is not always available. With roger., you can practise independently between lessons.

Review mistakes straight away

After each readback, you can see which required details were correct and what is worth practising again.

Your first radio call

This is the feedback you get on a task, in the app you also practice with real voice input.
