(these chi-square tests, what is the association? What % scored high among US students? What % scored high among Saudi students? What is the difference in proportion? Chi-square is not for association (such as a correlation), it should be telling you if there is a significant difference in proportion between two different groups.
Begin your results with a summary statement that sets up what is to follow- what is the bottom line? are knowledge scores high overall? are differences between the groups significant or not? this becomes very wordy and bounces around which challenges comprehension.)
