Rutgers University researchers surveyed 71,300 undergraduate students between Fall 2012 and Spring 2013 semesters to study the extent of student-admitted academic integrity and dishonesty in completing requirements for coursework. 

Of the 71300 students who responded to the survey: 

• 12121 respondents said they had deliberately cheated on at least one test
• 28520 respondents said they had deliberately cheated on at least one written assignment or project
• 9982 respondents said they had deliberately cheated on at least one test and on at least one written assignment or project

Based on the responses of the survey, how many students said they had deliberately cheated on at least one test or on at least one written assignment or project?
