The response came with a delay, but they still provided consultation. The course is really good; I wouldn't say it solves all problems, but it can help beginners. Some aspects were familiar to me, while I was unaware of others, so overall, my impression is positive. The price is very attractive; this course can help you start and master working with wb, covering the main aspects. Additionally, they are launching a new course, and those who purchase the current one at the old price will receive the updated version for free, even though the price of the new course is significantly higher. It's unclear whether this is a coincidence or a well-thought-out move. But I am definitely sure that the course is worth the money, and the updated version even more so.
