"Beyond Level 4" online course

[volganevariver]

Hello everyone!

I'm an ATC from Moscow Russia and would like to ask controllers and pilots if anybody has ever tried out the "Beyond Level 4" online course by RMIT Australia available on the RELTA.org ? Is it worth 400$?

There is also the "RELTA Preparation for Air Traffic Controllers" course at 100$? Can anyone share your thoughts on it?

I'm getting prepared for an upcoming english language test and desperately aiming to reach ICAO level 6. So I'd appreciate any assistance and feedback!

Cheers.
