Over a third of applicants to George Mason University don't get in. Successful applicants will need strong grades and, in many cases, solid standardized test scores. George Mason has test-optional admissions for students with a GPA of 3.5 or higher and a class rank in the top 20%. In the graph above, the blue and green dots represent accepted students. You can see a pretty clear division at a 3.0 GPA - very few students with a lower average were admitted. On the test front, most George Mason students scored 1500 or higher on the SAT or 21 or higher on the ACT. Higher test scores and grades obviously improve your chances of getting an acceptance letter, and almost no students with "A" averages and decent SAT scores were rejected.
Note that there are a few red dots (rejected students) and yellow dots (waitlisted students) hidden behind the green and blue in the middle of the graph. Some students with grades that were on target for George Mason did not get accepted. Note also that a few students were accepted with test scores and grades a bit below the norm. This is because George Mason has holistic admissions. GMU takes into consideration the rigor of your high school courses, your personal statment (which is much like the Common Application short answer), extracurricular activities, and a counselor letter of recommendation.
