To get a better idea, you should:
* Check the William & Mary admissions website: Look for information on transfer admissions, including the general academic qualifications of successful applicants. This might give you a range or some descriptive language about GPA expectations.
* Contact the William & Mary admissions office directly: They are the best source for this type of information. They may not give you a precise average, but they can likely give you a sense of the competitive GPA range.
Keep in mind that GPA is just one factor in the admissions decision. Course rigor, extracurricular activities, letters of recommendation, and essays all play significant roles.
