The name Supel makes me think of a knot and the way several small difficulties can become tangled in a learning task. Finding one connection to examine can make the whole problem feel less overwhelming. That is the idea I associate with [Supel learning connections](https://supel.edu.pl). I like explanations that take time to identify where confusion begins instead of presenting the full solution immediately. The first useful step may be small, but understanding it can make the next question much clearer.
