On November 10, 2014, the APEC meeting was held in Beijing, and a service department needed to recruit volunteers from university students. Volunteers recruited had to take part in both a written exam and an interview. The 60 university students who participated in the written exam were divided into groups based on their scores: Group 1 [75, 80) had 3 people, Group 2 [80, 85) had 21 people, Group 3 [85, 90) had 18 people, Group 4 [90, 95) had 12 people, and Group 5 [95, 100) had 6 people.
