What does world rank percentile mean? How is it calculated?
The percentiles go from 0 (worst) to 99 (best). This shows you where you are with relation to all other users in the world – for example;if your percentile is 92 then you are in the top 8% of users. (Specifically, you are in the top 8% but not in the top 7%.) You can also think of this as the percentage of all users that you are smarter than, so a percentile score of 92 means you are smarter than 92% of all users.
