Testimonials
The coolest thing was that it was not the "dry" knowledge, there were only a lot of exercises and repetitions on a regular basis, and that all the questions asked during the training were answered by the instructor, which definitely facilitated the understanding of the issue.

The most striking thing for me was the trainer's use of talking to the group in the way "Look", "Look", "Now use this command" - this is a fairly well-known and effective method of maintaining focus among listeners. In addition, extensive knowledge of the teacher. which he can convey in an accessible way.
