Hi,
Now the judge center is down for some time, there is currently a lack in training material for judges willing to advance. While the Judge booth offers some options for L1 candidates, that material is less suited for L2 candidates, does not ask policy questions, and is not in the best format for this purpose.
So, I've created a project for this:
