Rough rating comparison
This is not a chess rating. The estimate depends on these twelve positions and whether you’ve practiced them before.
The model picks the rating band that best fits your answers. The bars summarize the original source games, which include bot accounts. They do not measure human success rates on this test.
The practice bank is easier than the full dataset, so the comparison can overestimate your strength. The model still needs checking against independent test responses.
