Also, let me remind you. As part of this course, there is a Telegram group in which I answer all participants' questions online and help them along the way.
Entrance to the group is free, via the invitation link (indicated below). There is currently no limit on the number of participants.
In the specified group, ask absolutely any questions, as part of our training. Watch the video, try to repeat it. It turned out great. If something didn't work out, write a question in the group. I will answer and help everyone.
