Learning progress is more meaningful than a demonstration
If you want to try dance classes in Stuttgart, don't judge them by how difficult the demonstrated moves are. A teacher can be an impressive dancer and still skip important intermediate steps. To assess the class, focus on the distance between your first uncertain attempt and a movement you can repeat with a little more confidence.
This progress can be small. Maybe you recognize for the first time which foot your weight is on, or find your way back to the beat after a mistake. For more complex sequences, practicing arms and legs separately is a useful way to learn. It reduces the number of tasks you have to do at once without losing sight of how they fit together later.
Always assess the same short sequence, not several moves of varying difficulty. Otherwise, you may confuse the level of difficulty with the quality of the explanation. In partner dancing, an experienced partner can also discreetly compensate for mistakes. So take your own sense of direction into account too: Do you know which foot to start on, which direction to go, and what the rhythm is? Dancing together doesn't require you to be in a romantic relationship, as the guide to dance classes without a romantic relationship explains.
A single class gives you a snapshot. It lets you make an informed judgment about your learning experience, but doesn't tell you how every future class will be structured.
