Question: Where do half of the black college students rank in terms of their performance relative to the rest of their class?
Sentence: For example, about half of black college students rank in the bottom 20 percent of their classes, black law school graduates are four times as likely to fail bar exams as are whites, and interracial friendships are more likely to form among students with relatively similar levels of academic preparation; thus, blacks and Hispanics are more socially integrated on campuses where they are less academically mismatched.
Answer in sentence: yes
