The girls are listed from G1 to G4 with G1 being the highest scoring girl to G4 being the lowest scoring girl. The same is done with the boys, B1 scored higher than B2

Now we know the highest scoring student scored 10.
Let's first assume that the highest scoring student is the highest scoring girl.
Since the lowest scoring by has 6, and the lowest score of all is 4, that must be a girl.
That makes the higher scoring boy score an 8.
Now we need to make the other assumption.
Let's assume it's the higher scoring boy who got the 10.
With this assumption, we have the lowest girl score is 6 and the highest is 8.
There are only 3 scores the girls could have had, 6, 7, and 8.
There are 4 girls. That means two must have had the same score, but we were told each student had a different score, so this second assumption is incorrect. The first assumption is correct, and the higher boys' score is 8.
Wow! I get it now. Thank you so much @mathstudent55 for answering my question.
