education platform Guru99.com analyzed six different metrics: average IQ, graduation rates, percentage of the population with low literacy rates, average SAT scores,
% of the states that don’t have a high school diploma or GED and GDP per capita. These were then given a score out of 10 and combined to give a total score of 60.
Someone should tell the idiots at that "education platform" that states don't get "...a high school diploma or GED and GDP...", people get those. And if they did, the "per capita" of a state would either be 100% or 0% since there is only one state per state.
That tells you everything you need to know about the intelligence of the people at Guru99.com.
