Ambrose99 you are wrong. Fewer boys are going to university. 
Two generations or so ago first year entrance was 60% male to 40% female, with completion rates  in 1971 being 68% male and 32% female - and there were long and loud complaints that the imbalance was sexist and had to be fixed. 
Fast forward one generation and the imbalance was precisely reversed: 60% female to 40% male. 
Fast forward another generation and it has progressed even further. If you want to look at completion rates girls were getting 60% of the degrees by the turn of the century.
.
As soon as the balance tilted toward girls there was a long list of reasons why it was boys fault they weren't getting into university in equal numbers to girls. This has continued with all sorts of victim blaming attacks on boys.  But as the results of these tests show, as the article clearly states, there is no difference in performance between boys and girls in high school science so it is clearly not a matter of intrinsic ability.
