An objective question is one with a right or wrong answer, and which can be graded with an answer key. On most standardized tests, an objective question is asked in the form of multiple choice or "true or false." In contrast, a subjective question is one without a clear cut right or wrong answer, and therefore allows the test taker or respondent to answer with some creativity. Subjective questions on tests are often answered in the form of an essay.
Most questions on the GMAT are objective, and they are grouped together in the quantitative and verbal sections. However, the GMAT also has an analytical writing section, which are subjective questions because they are written in essay form and graded on a scale of 0 to 6 by human beings. There are two essays; in one essay, the test taker analyzes an argument, and in the second essay they analyze a specific issue.
However, the GMAT essays are not the only opportunity that MBA applicants have to answer subjective questions. Most schools require applicants to answer one or more essay questions, along with submitting their GMAT scores and resumes. These subjective essays frequently have word limits. For example, according to the Harvard Business School, their essay questions for students applying in 2011 include "What are your three most substantial accomplishments and why do you view them as such?" and "What have you learned from a mistake?"
In addition to the written subjective questions found on the GMAT and application essays, some MBA programs will conduct face-to-face interviews with applicants. In these interviews, a representative from the school may ask various subjective questions such as "What are your goals post-graduation?" or "Why are you going back to school now?" Much like the application essay, the subjective questions of an interview allow the applicant to personalize their responses in order to distinguish themselves from other potential students.
