Any beginner and even amateur sculptors should attend this class. The course is very intensive, very demanding and requires a lot of attention, but you learn a lot.
It shows you not only how to properly use the tools but also how to position your body so as not to tire quickly. It teaches you how to look at your work and that of others. The course does not show just technical elements, it also teaches a way of thinking and understanding sculpture.
After the course you will not see a sculpture in the same way.
I highly recommend it.
