Just like learning a foreign language - you can learn grammar, syntax, spelling and spend years at school, or just go abroad for a long vacation and learn a language through conversion, as you use it in reality. The course that you have in front of you is fully compatible with this second approach, which in our opinion allows for a much more effective learning. You will see that it can also be extremely pleasant!
Therefore, we invite you to familiarize yourself with the course!
