No matter how talented a pedagogue may be, for students, to assimilate information for several hours in a row is humanly impossible. Our ability to retain knowledge depends on our level of expertise at the beginning of the training, and on personal factors such as fatigue, or simply psychological availability on the day of training.
Furthermore, to illustrate his point, a trainer needs to provide examples, which are not necessarily those on which you work daily.
Finally, throughout the course, there are inevitably times when one is presented with matter that seems easy and already mastered.
In contrast, you call the coach only when needed to cover the point or points that are problematic.
With a coach, you work on your solution, in relatively short sessions: that allows you to stay focused and enjoy 100% of the time.
Coaching brings a direct added value to your database and gives you the opportunity to increase your knowledge and therefore your autonomy.
