Wow it does say the test set problems are harder than the training set problems. I didn’t expect that.
But it’s not an enormous difference: the example model that got 53% on the public training set got 38% on the public test set. It got only 24% on the private test set, even though it’s supposed to be equally hard, maybe because “trial and error” fitted the model to the public test set as well as the public training set.

The other example model got 32%, 30%, and 22%.
