A Persistent Gender Gap For Math/Verbal Skills
This is an interesting study: Gender Gap Persists At Highest Levels Of Standardized Testing. Over a 30 year time period, the test scores of boys and girls show that in the top 5% of the bell curve, boys do better than girls at math/science tests at about a 4:1 ratio. During the same period, top performing girls only do slightly better than the boys in verbal reasoning and writing ability tests.

I wonder if this is related to autism being more common in boys than in girls.
“Autism is about four times more common in boys than girls.”
